| 519 | <h2><a id="introduction">Introduction</a></h2> |
| 520 | <p>CUPS provides the "cups" library to talk to the different parts of CUPS and with Internet Printing Protocol (IPP) printers. The "cups" library functions are accessed by including the <code><cups/cups.h></code> header.</p> |
| 521 | <p>CUPS is based on the Internet Printing Protocol ("IPP"), which allows clients (applications) to communicate with a server (the scheduler, printers, etc.) to get a list of destinations, send print jobs, and so forth. You identify which server you want to communicate with using a pointer to the opaque structure <code>http_t</code>. The <code>CUPS_HTTP_DEFAULT</code> constant can be used when you want to talk to the CUPS scheduler.</p> |
| 522 | <h3><a id="guidelines">Guidelines</a></h3> |
| 523 | <p>When writing software (other than printer drivers) that uses the "cups" library:</p> |
| 524 | <ul> |
| 525 | <li>Do not use undocumented or deprecated APIs,</li> |
| 526 | <li>Do not rely on pre-configured printers,</li> |
| 527 | <li>Do not assume that printers support specific features or formats, and</li> |
| 528 | <li>Do not rely on implementation details (PPDs, etc.)</li> |
| 529 | </ul> |
| 530 | <p>CUPS is designed to insulate users and developers from the implementation details of printers and file formats. The goal is to allow an application to supply a print file in a standard format with the user intent ("print four copies, two-sided on A4 media, and staple each copy") and have the printing system manage the printer communication and format conversion needed.</p> |
| 531 | <p>Similarly, printer and job management applications can use standard query operations to obtain the status information in a common, generic form and use standard management operations to control the state of those printers and jobs.</p> |
| 532 | <blockquote> |
| 533 | <p><strong>Note:</strong></p> |
| 534 | <p>CUPS printer drivers necessarily depend on specific file formats and certain implementation details of the CUPS software. Please consult the Postscript and raster printer driver developer documentation on <a href="https://www.cups.org/documentation.html">CUPS.org</a> for more information.</p> |
| 535 | </blockquote> |
| 536 | <h3><a id="terms-used-in-this-document">Terms Used in This Document</a></h3> |
| 537 | <p>A <em>Destination</em> is a printer or print queue that accepts print jobs. A <em>Print</em> <em>Job</em> is a collection of one or more documents that are processed by a destination using options supplied when creating the job. A <em>Document</em> is a file (JPEG image, PDF file, etc.) suitable for printing. An <em>Option</em> controls some aspect of printing, such as the media used. <em>Media</em> is the sheets or roll that is printed on. An <em>Attribute</em> is an option encoded for an Internet Printing Protocol (IPP) request.</p> |
| 538 | <h3><a id="compiling-programs-that-use-the-cups-api">Compiling Programs That Use the CUPS API</a></h3> |
| 539 | <p>The CUPS libraries can be used from any C, C++, or Objective C program. The method of compiling against the libraries varies depending on the operating system and installation of CUPS. The following sections show how to compile a simple program (shown below) in two common environments.</p> |
| 540 | <p>The following simple program lists the available destinations:</p> |
| 541 | <pre><code>#include <stdio.h> |
| 542 | #include <cups/cups.h> |
| 543 | |
| 544 | int print_dest(void *user_data, unsigned flags, cups_dest_t *dest) |
| 545 | { |
| 546 | if (dest->instance) |
| 547 | printf("%s/%s\n", dest->name, dest->instance); |
| 548 | else |
| 549 | puts(dest->name); |
| 550 | |
| 551 | return (1); |
| 552 | } |
| 553 | |
| 554 | int main(void) |
| 555 | { |
| 556 | cupsEnumDests(CUPS_DEST_FLAGS_NONE, 1000, NULL, 0, 0, print_dest, NULL); |
| 557 | |
| 558 | return (0); |
| 559 | } |
| 560 | </code></pre> |
| 561 | <h4><a id="compiling-with-xcode">Compiling with Xcode</a></h4> |
| 562 | <p>In Xcode, choose <em>New</em> <em>Project...</em> from the <em>File</em> menu (or press SHIFT+CMD+N), then select the <em>Command</em> <em>Line</em> <em>Tool</em> under the macOS Application project type. Click <em>Next</em> and enter a name for the project, for example "firstcups". Click <em>Next</em> and choose a project directory. The click <em>Next</em> to create the project.</p> |
| 563 | <p>In the project window, click on the <em>Build</em> <em>Phases</em> group and expand the <em>Link</em> <em>Binary</em> <em>with</em> <em>Libraries</em> section. Click <em>+</em>, type "libcups" to show the library, and then double-click on <code>libcups.tbd</code>.</p> |
| 564 | <p>Finally, click on the <code>main.c</code> file in the sidebar and copy the example program to the file. Build and run (CMD+R) to see the list of destinations.</p> |
| 565 | <h4><a id="compiling-with-gcc">Compiling with GCC</a></h4> |
| 566 | <p>From the command-line, create a file called <code>simple.c</code> using your favorite editor, copy the example to this file, and save. Then run the following command to compile it with GCC and run it:</p> |
| 567 | <pre><code>gcc -o simple `cups-config --cflags` simple.c `cups-config --libs` |
| 568 | ./simple |
| 569 | </code></pre> |
| 570 | <p>The <code>cups-config</code> command provides the compiler flags (<code>cups-config --cflags</code>) and libraries (<code>cups-config --libs</code>) needed for the local system.</p> |
| 571 | <h2><a id="working-with-destinations">Working with Destinations</a></h2> |
| 572 | <p>Destinations, which in CUPS represent individual printers or classes (collections or pools) of printers, are represented by the <code>cups_dest_t</code> structure which includes the name (<code>name</code>), instance (<code>instance</code>, saved options/settings), whether the destination is the default for the user (<code>is_default</code>), and the options and basic information associated with that destination (<code>num_options</code> and <code>options</code>).</p> |
| 573 | <p>Historically destinations have been manually maintained by the administrator of a system or network, but CUPS also supports dynamic discovery of destinations on the current network.</p> |
| 574 | <h3><a id="finding-available-destinations">Finding Available Destinations</a></h3> |
| 575 | <p>The <code>cupsEnumDests</code> function finds all of the available destinations:</p> |
| 576 | <pre><code> int |
| 577 | cupsEnumDests(unsigned flags, int msec, int *cancel, |
| 578 | cups_ptype_t type, cups_ptype_t mask, |
| 579 | cups_dest_cb_t cb, void *user_data) |
| 580 | </code></pre> |
| 581 | <p>The <code>flags</code> argument specifies enumeration options, which at present must be <code>CUPS_DEST_FLAGS_NONE</code>.</p> |
| 582 | <p>The <code>msec</code> argument specifies the maximum amount of time that should be used for enumeration in milliseconds - interactive applications should keep this value to 5000 or less when run on the main thread.</p> |
| 583 | <p>The <code>cancel</code> argument points to an integer variable that, when set to a non-zero value, will cause enumeration to stop as soon as possible. It can be <code>NULL</code> if not needed.</p> |
| 584 | <p>The <code>type</code> and <code>mask</code> arguments are bitfields that allow the caller to filter the destinations based on categories and/or capabilities. The destination's "printer-type" value is masked by the <code>mask</code> value and compared to the <code>type</code> value when filtering. For example, to only enumerate destinations that are hosted on the local system, pass <code>CUPS_PRINTER_LOCAL</code> for the <code>type</code> argument and <code>CUPS_PRINTER_DISCOVERED</code> for the <code>mask</code> argument. The following constants can be used for filtering:</p> |
| 585 | <ul> |
| 586 | <li><code>CUPS_PRINTER_CLASS</code>: A collection of destinations.</li> |
| 587 | <li><code>CUPS_PRINTER_FAX</code>: A facsimile device.</li> |
| 588 | <li><code>CUPS_PRINTER_LOCAL</code>: A local printer or class. This constant has the value 0 (no bits set) and is only used for the <code>type</code> argument and is paired with the <code>CUPS_PRINTER_REMOTE</code> or <code>CUPS_PRINTER_DISCOVERED</code> constant passed in the <code>mask</code> argument.</li> |
| 589 | <li><code>CUPS_PRINTER_REMOTE</code>: A remote (shared) printer or class.</li> |
| 590 | <li><code>CUPS_PRINTER_DISCOVERED</code>: An available network printer or class.</li> |
| 591 | <li><code>CUPS_PRINTER_BW</code>: Can do B&W printing.</li> |
| 592 | <li><code>CUPS_PRINTER_COLOR</code>: Can do color printing.</li> |
| 593 | <li><code>CUPS_PRINTER_DUPLEX</code>: Can do two-sided printing.</li> |
| 594 | <li><code>CUPS_PRINTER_STAPLE</code>: Can staple output.</li> |
| 595 | <li><code>CUPS_PRINTER_COLLATE</code>: Can quickly collate copies.</li> |
| 596 | <li><code>CUPS_PRINTER_PUNCH</code>: Can punch output.</li> |
| 597 | <li><code>CUPS_PRINTER_COVER</code>: Can cover output.</li> |
| 598 | <li><code>CUPS_PRINTER_BIND</code>: Can bind output.</li> |
| 599 | <li><code>CUPS_PRINTER_SORT</code>: Can sort output (mailboxes, etc.)</li> |
| 600 | <li><code>CUPS_PRINTER_SMALL</code>: Can print on Letter/Legal/A4-size media.</li> |
| 601 | <li><code>CUPS_PRINTER_MEDIUM</code>: Can print on Tabloid/B/C/A3/A2-size media.</li> |
| 602 | <li><code>CUPS_PRINTER_LARGE</code>: Can print on D/E/A1/A0-size media.</li> |
| 603 | <li><code>CUPS_PRINTER_VARIABLE</code>: Can print on rolls and custom-size media.</li> |
| 604 | </ul> |
| 605 | <p>The <code>cb</code> argument specifies a function to call for every destination that is found:</p> |
| 606 | <pre><code>typedef int (*cups_dest_cb_t)(void *user_data, |
| 607 | unsigned flags, |
| 608 | cups_dest_t *dest); |
| 609 | </code></pre> |
| 610 | <p>The callback function receives a copy of the <code>user_data</code> argument along with a bitfield (<code>flags</code>) and the destination that was found. The <code>flags</code> argument can have any of the following constant (bit) values set:</p> |
| 611 | <ul> |
| 612 | <li><code>CUPS_DEST_FLAGS_MORE</code>: There are more destinations coming.</li> |
| 613 | <li><code>CUPS_DEST_FLAGS_REMOVED</code>: The destination has gone away and should be removed from the list of destinations a user can select.</li> |
| 614 | <li><code>CUPS_DEST_FLAGS_ERROR</code>: An error occurred. The reason for the error can be found by calling the <code>cupsLastError</code> and/or <code>cupsLastErrorString</code> functions.</li> |
| 615 | </ul> |
| 616 | <p>The callback function returns 0 to stop enumeration or 1 to continue.</p> |
| 617 | <blockquote> |
| 618 | <p><strong>Note:</strong></p> |
| 619 | <p>The callback function will likely be called multiple times for the same destination, so it is up to the caller to suppress any duplicate destinations.</p> |
| 620 | </blockquote> |
| 621 | <p>The following example shows how to use <code>cupsEnumDests</code> to get a filtered array of destinations:</p> |
| 622 | <pre><code>typedef struct |
| 623 | { |
| 624 | int num_dests; |
| 625 | cups_dest_t *dests; |
| 626 | } my_user_data_t; |
| 627 | |
| 628 | int |
| 629 | my_dest_cb(my_user_data_t *user_data, unsigned flags, |
| 630 | cups_dest_t *dest) |
| 631 | { |
| 632 | if (flags & CUPS_DEST_FLAGS_REMOVED) |
| 633 | { |
| 634 | /* |
| 635 | * Remove destination from array... |
| 636 | */ |
| 637 | |
| 638 | user_data->num_dests = |
| 639 | cupsRemoveDest(dest->name, dest->instance, |
| 640 | user_data->num_dests, |
| 641 | &(user_data->dests)); |
| 642 | } |
| 643 | else |
| 644 | { |
| 645 | /* |
| 646 | * Add destination to array... |
| 647 | */ |
| 648 | |
| 649 | user_data->num_dests = |
| 650 | cupsCopyDest(dest, user_data->num_dests, |
| 651 | &(user_data->dests)); |
| 652 | } |
| 653 | |
| 654 | return (1); |
| 655 | } |
| 656 | |

| 689 | <p>The <code>num_options</code> and <code>options</code> members of the <code>cups_dest_t</code> structure provide basic attributes about the destination in addition to the user default options and values for that destination. The following names are predefined for various destination attributes:</p> |
| 690 | <ul> |
| 691 | <li>"auth-info-required": The type of authentication required for printing to this destination: "none", "username,password", "domain,username,password", or "negotiate" (Kerberos).</li> |
| 692 | <li>"printer-info": The human-readable description of the destination such as "My Laser Printer".</li> |
| 693 | <li>"printer-is-accepting-jobs": "true" if the destination is accepting new jobs, "false" otherwise.</li> |
| 694 | <li>"printer-is-shared": "true" if the destination is being shared with other computers, "false" otherwise.</li> |
| 695 | <li>"printer-location": The human-readable location of the destination such as "Lab 4".</li> |
| 696 | <li>"printer-make-and-model": The human-readable make and model of the destination such as "ExampleCorp LaserPrinter 4000 Series".</li> |
| 697 | <li>"printer-state": "3" if the destination is idle, "4" if the destination is printing a job, and "5" if the destination is stopped.</li> |
| 698 | <li>"printer-state-change-time": The UNIX time when the destination entered the current state.</li> |
| 699 | <li>"printer-state-reasons": Additional comma-delimited state keywords for the destination such as "media-tray-empty-error" and "toner-low-warning".</li> |
| 700 | <li>"printer-type": The <code>cups_ptype_t</code> value associated with the destination.</li> |
| 701 | <li>"printer-uri-supported": The URI associated with the destination; if not set, this destination was discovered but is not yet setup as a local printer.</li> |
| 702 | </ul> |
| 703 | <p>Use the <code>cupsGetOption</code> function to retrieve the value. For example, the following code gets the make and model of a destination:</p> |
| 704 | <pre><code>const char *model = cupsGetOption("printer-make-and-model", |
| 705 | dest->num_options, |
| 706 | dest->options); |

| 708 | <h3><a id="detailed-destination-information">Detailed Destination Information</a></h3> |
| 709 | <p>Once a destination has been chosen, the <code>cupsCopyDestInfo</code> function can be used to gather detailed information about the destination:</p> |
| 710 | <pre><code>cups_dinfo_t * |
| 711 | cupsCopyDestInfo(http_t *http, cups_dest_t *dest); |
| 712 | </code></pre> |
| 713 | <p>The <code>http</code> argument specifies a connection to the CUPS scheduler and is typically the constant <code>CUPS_HTTP_DEFAULT</code>. The <code>dest</code> argument specifies the destination to query.</p> |
| 714 | <p>The <code>cups_dinfo_t</code> structure that is returned contains a snapshot of the supported options and their supported, ready, and default values. It also can report constraints between different options and values, and recommend changes to resolve those constraints.</p> |
| 715 | <h4><a id="getting-supported-options-and-values">Getting Supported Options and Values</a></h4> |
| 716 | <p>The <code>cupsCheckDestSupported</code> function can be used to test whether a particular option or option and value is supported:</p> |

| 718 | cupsCheckDestSupported(http_t *http, cups_dest_t *dest, |
| 719 | cups_dinfo_t *info, |
| 720 | const char *option, |
| 721 | const char *value); |
| 722 | </code></pre> |
| 723 | <p>The <code>option</code> argument specifies the name of the option to check. The following constants can be used to check the various standard options:</p> |
| 724 | <ul> |
| 725 | <li><code>CUPS_COPIES</code>: Controls the number of copies that are produced.</li> |
| 726 | <li><code>CUPS_FINISHINGS</code>: A comma-delimited list of integer constants that control the finishing processes that are applied to the job, including stapling, punching, and folding.</li> |
| 727 | <li><code>CUPS_MEDIA</code>: Controls the media size that is used, typically one of the following: <code>CUPS_MEDIA_3X5</code>, <code>CUPS_MEDIA_4X6</code>, <code>CUPS_MEDIA_5X7</code>, <code>CUPS_MEDIA_8X10</code>, <code>CUPS_MEDIA_A3</code>, <code>CUPS_MEDIA_A4</code>, <code>CUPS_MEDIA_A5</code>, <code>CUPS_MEDIA_A6</code>, <code>CUPS_MEDIA_ENV10</code>, <code>CUPS_MEDIA_ENVDL</code>, <code>CUPS_MEDIA_LEGAL</code>, <code>CUPS_MEDIA_LETTER</code>, <code>CUPS_MEDIA_PHOTO_L</code>, <code>CUPS_MEDIA_SUPERBA3</code>, or <code>CUPS_MEDIA_TABLOID</code>.</li> |
| 728 | <li><code>CUPS_MEDIA_SOURCE</code>: Controls where the media is pulled from, typically either <code>CUPS_MEDIA_SOURCE_AUTO</code> or <code>CUPS_MEDIA_SOURCE_MANUAL</code>.</li> |
| 729 | <li><code>CUPS_MEDIA_TYPE</code>: Controls the type of media that is used, typically one of the following: <code>CUPS_MEDIA_TYPE_AUTO</code>, <code>CUPS_MEDIA_TYPE_ENVELOPE</code>, <code>CUPS_MEDIA_TYPE_LABELS</code>, <code>CUPS_MEDIA_TYPE_LETTERHEAD</code>, <code>CUPS_MEDIA_TYPE_PHOTO</code>, <code>CUPS_MEDIA_TYPE_PHOTO_GLOSSY</code>, <code>CUPS_MEDIA_TYPE_PHOTO_MATTE</code>, <code>CUPS_MEDIA_TYPE_PLAIN</code>, or <code>CUPS_MEDIA_TYPE_TRANSPARENCY</code>.</li> |
| 730 | <li><code>CUPS_NUMBER_UP</code>: Controls the number of document pages that are placed on each media side.</li> |
| 731 | <li><code>CUPS_ORIENTATION</code>: Controls the orientation of document pages placed on the media: <code>CUPS_ORIENTATION_PORTRAIT</code> or <code>CUPS_ORIENTATION_LANDSCAPE</code>.</li> |
| 732 | <li><code>CUPS_PRINT_COLOR_MODE</code>: Controls whether the output is in color (<code>CUPS_PRINT_COLOR_MODE_COLOR</code>), grayscale (<code>CUPS_PRINT_COLOR_MODE_MONOCHROME</code>), or either (<code>CUPS_PRINT_COLOR_MODE_AUTO</code>).</li> |
| 733 | <li><code>CUPS_PRINT_QUALITY</code>: Controls the generate quality of the output: <code>CUPS_PRINT_QUALITY_DRAFT</code>, <code>CUPS_PRINT_QUALITY_NORMAL</code>, or <code>CUPS_PRINT_QUALITY_HIGH</code>.</li> |
| 734 | <li><code>CUPS_SIDES</code>: Controls whether prints are placed on one or both sides of the media: <code>CUPS_SIDES_ONE_SIDED</code>, <code>CUPS_SIDES_TWO_SIDED_PORTRAIT</code>, or <code>CUPS_SIDES_TWO_SIDED_LANDSCAPE</code>.</li> |
| 735 | </ul> |
| 736 | <p>If the <code>value</code> argument is <code>NULL</code>, the <code>cupsCheckDestSupported</code> function returns whether the option is supported by the destination. Otherwise, the function returns whether the specified value of the option is supported.</p> |
| 737 | <p>The <code>cupsFindDestSupported</code> function returns the IPP attribute containing the supported values for a given option:</p> |
| 738 | <pre><code> ipp_attribute_t * |
| 739 | cupsFindDestSupported(http_t *http, cups_dest_t *dest, |
| 740 | cups_dinfo_t *dinfo, |
| 741 | const char *option); |
| 742 | </code></pre> |
| 743 | <p>For example, the following code prints the supported finishing processes for a destination, if any, to the standard output:</p> |
| 744 | <pre><code>cups_dinfo_t *info = cupsCopyDestInfo(CUPS_HTTP_DEFAULT, |
| 745 | dest); |

| 758 | } |
| 759 | else |
| 760 | puts("finishings not supported."); |
| 761 | </code></pre> |
| 762 | <p>The "job-creation-attributes" option can be queried to get a list of supported options. For example, the following code prints the list of supported options to the standard output:</p> |
| 763 | <pre><code>ipp_attribute_t *attrs = |
| 764 | cupsFindDestSupported(CUPS_HTTP_DEFAULT, dest, info, |
| 765 | "job-creation-attributes"); |

| 768 | for (i = 0; i < count; i ++) |
| 769 | puts(ippGetString(attrs, i, NULL)); |
| 770 | </code></pre> |
| 771 | <h4><a id="getting-default-values">Getting Default Values</a></h4> |
| 772 | <p>There are two sets of default values - user defaults that are available via the <code>num_options</code> and <code>options</code> members of the <code>cups_dest_t</code> structure, and destination defaults that available via the <code>cups_dinfo_t</code> structure and the <code>cupsFindDestDefault</code> function which returns the IPP attribute containing the default value(s) for a given option:</p> |
| 773 | <pre><code>ipp_attribute_t * |
| 774 | cupsFindDestDefault(http_t *http, cups_dest_t *dest, |
| 775 | cups_dinfo_t *dinfo, |
| 776 | const char *option); |
| 777 | </code></pre> |
| 778 | <p>The user defaults from <code>cupsGetOption</code> should always take preference over the destination defaults. For example, the following code prints the default finishings value(s) to the standard output:</p> |
| 779 | <pre><code>const char *def_value = |
| 780 | cupsGetOption(CUPS_FINISHINGS, dest->num_options, |
| 781 | dest->options); |

| 797 | printf(",%d", ippGetInteger(def_attr, i)); |
| 798 | putchar('\n'); |
| 799 | } |
| 800 | </code></pre> |
| 801 | <h4><a id="getting-ready-loaded-values">Getting Ready (Loaded) Values</a></h4> |
| 802 | <p>The finishings and media options also support queries for the ready, or loaded, values. For example, a printer may have punch and staple finishers installed but be out of staples - the supported values will list both punch and staple finishing processes but the ready values will only list the punch processes. Similarly, a printer may support hundreds of different sizes of media but only have a single size loaded at any given time - the ready values are limited to the media that is actually in the printer.</p> |
| 803 | <p>The <code>cupsFindDestReady</code> function finds the IPP attribute containing the ready values for a given option:</p> |
| 804 | <pre><code>ipp_attribute_t * |
| 805 | cupsFindDestReady(http_t *http, cups_dest_t *dest, |
| 806 | cups_dinfo_t *dinfo, const char *option); |
| 807 | </code></pre> |
| 808 | <p>For example, the following code lists the ready finishing processes:</p> |
| 809 | <pre><code>ipp_attribute_t *ready_finishings = |
| 810 | cupsFindDestReady(CUPS_HTTP_DEFAULT, dest, info, |
| 811 | CUPS_FINISHINGS); |

| 815 | int i, count = ippGetCount(ready_finishings); |
| 816 | |
| 817 | puts("finishings ready:"); |
| 818 | for (i = 0; i < count; i ++) |
| 819 | printf(" %d\n", ippGetInteger(ready_finishings, i)); |
| 820 | } |
| 821 | else |
| 822 | puts("no finishings are ready."); |
| 823 | </code></pre> |
| 824 | <h4><a id="media-size-options">Media Size Options</a></h4> |
| 825 | <p>CUPS provides functions for querying the dimensions and margins for each of the supported media size options. The <code>cups_size_t</code> structure is used to describe a media size:</p> |
| 826 | <pre><code>typedef struct cups_size_s |
| 827 | { |
| 828 | char media[128]; |
| 829 | int width, length; |
| 830 | int bottom, left, right, top; |
| 831 | } cups_size_t; |
| 832 | </code></pre> |
| 833 | <p>The <code>width</code> and <code>length</code> members specify the dimensions of the media in hundredths of millimeters (1/2540th of an inch). The <code>bottom</code>, <code>left</code>, <code>right</code>, and <code>top</code> members specify the margins of the printable area, also in hundredths of millimeters.</p> |
| 834 | <p>The <code>cupsGetDestMediaByName</code> and <code>cupsGetDestMediaBySize</code> functions lookup the media size information using a standard media size name or dimensions in hundredths of millimeters:</p> |
| 835 | <pre><code>int |
| 836 | cupsGetDestMediaByName(http_t *http, cups_dest_t *dest, |
| 837 | cups_dinfo_t *dinfo, |
| 838 | const char *media, |
| 839 | unsigned flags, cups_size_t *size); |
| 840 | |
| 841 | int |
| 842 | cupsGetDestMediaBySize(http_t *http, cups_dest_t *dest, |
| 843 | cups_dinfo_t *dinfo, |
| 844 | int width, int length, |
| 845 | unsigned flags, cups_size_t *size); |
| 846 | </code></pre> |
| 847 | <p>The <code>media</code>, <code>width</code>, and <code>length</code> arguments specify the size to lookup. The <code>flags</code> argument specifies a bitfield controlling various lookup options:</p> |
| 848 | <ul> |
| 849 | <li><code>CUPS_MEDIA_FLAGS_DEFAULT</code>: Find the closest size supported by the printer.</li> |
| 850 | <li><code>CUPS_MEDIA_FLAGS_BORDERLESS</code>: Find a borderless size.</li> |
| 851 | <li><code>CUPS_MEDIA_FLAGS_DUPLEX</code>: Find a size compatible with two-sided printing.</li> |
| 852 | <li><code>CUPS_MEDIA_FLAGS_EXACT</code>: Find an exact match for the size.</li> |
| 853 | <li><code>CUPS_MEDIA_FLAGS_READY</code>: If the printer supports media sensing or configuration of the media in each tray/source, find the size amongst the "ready" media.</li> |
| 854 | </ul> |
| 855 | <p>If a matching size is found for the destination, the size information is stored in the structure pointed to by the <code>size</code> argument and 1 is returned. Otherwise 0 is returned.</p> |
| 856 | <p>For example, the following code prints the margins for two-sided printing on US Letter media:</p> |
| 857 | <pre><code>cups_size_t size; |
| 858 | |
| 859 | if (cupsGetDestMediaByName(CUPS_HTTP_DEFAULT, dest, info, |

| 862 | { |
| 863 | puts("Margins for duplex US Letter:"); |

| 869 | else |
| 870 | puts("Margins for duplex US Letter are not available."); |
| 871 | </code></pre> |
| 872 | <p>You can also enumerate all of the sizes that match a given <code>flags</code> value using the <code>cupsGetDestMediaByIndex</code> and <code>cupsGetDestMediaCount</code> functions:</p> |
| 873 | <pre><code>int |

| 884 | int i; |
| 885 | int count = cupsGetDestMediaCount(CUPS_HTTP_DEFAULT, |

| 1009 | <h2><a id="sending-ipp-requests">Sending IPP Requests</a></h2> |
| 1010 | <p>CUPS provides a rich API for sending IPP requests to the scheduler or printers, typically from management or utility applications whose primary purpose is not to send print jobs.</p> |
| 1011 | <h3><a id="connecting-to-the-scheduler-or-printer">Connecting to the Scheduler or Printer</a></h3> |
| 1012 | <p>The connection to the scheduler or printer is represented by the HTTP connection type <code>http_t</code>. The <code>cupsConnectDest</code> function connects to the scheduler or printer associated with the destination:</p> |
| 1013 | <pre><code>http_t * |
| 1014 | cupsConnectDest(cups_dest_t *dest, unsigned flags, int msec, |
| 1015 | int *cancel, char *resource, |
| 1016 | size_t resourcesize, cups_dest_cb_t cb, |
| 1017 | void *user_data); |
| 1018 | </code></pre> |
| 1019 | <p>The <code>dest</code> argument specifies the destination to connect to.</p> |
| 1020 | <p>The <code>flags</code> argument specifies whether you want to connect to the scheduler (<code>CUPS_DEST_FLAGS_NONE</code>) or device/printer (<code>CUPS_DEST_FLAGS_DEVICE</code>) associated with the destination.</p> |
| 1021 | <p>The <code>msec</code> argument specifies how long you are willing to wait for the connection to be established in milliseconds. Specify a value of <code>-1</code> to wait indefinitely.</p> |
| 1022 | <p>The <code>cancel</code> argument specifies the address of an integer variable that can be set to a non-zero value to cancel the connection. Specify a value of <code>NULL</code> to not provide a cancel variable.</p> |
| 1023 | <p>The <code>resource</code> and <code>resourcesize</code> arguments specify the address and size of a character string array to hold the path to use when sending an IPP request.</p> |
| 1024 | <p>The <code>cb</code> and <code>user_data</code> arguments specify a destination callback function that returns 1 to continue connecting or 0 to stop. The destination callback work the same way as the one used for the <code>cupsEnumDests</code> function.</p> |
| 1025 | <p>On success, a HTTP connection is returned that can be used to send IPP requests and get IPP responses.</p> |
| 1026 | <p>For example, the following code connects to the printer associated with a destination with a 30 second timeout:</p> |
| 1027 | <pre><code>char resource[256]; |
| 1028 | http_t *http = cupsConnectDest(dest, CUPS_DEST_FLAGS_DEVICE, |
| 1029 | 30000, NULL, resource, |
| 1030 | sizeof(resource), NULL, NULL); |
| 1031 | </code></pre> |
| 1032 | <h3><a id="creating-an-ipp-request">Creating an IPP Request</a></h3> |
| 1033 | <p>IPP requests are represented by the IPP message type <code>ipp_t</code> and each IPP attribute in the request is representing using the type <code>ipp_attribute_t</code>. Each IPP request includes an operation code (<code>IPP_OP_CREATE_JOB</code>, <code>IPP_OP_GET_PRINTER_ATTRIBUTES</code>, etc.) and a 32-bit integer identifier.</p> |
| 1034 | <p>The <code>ippNewRequest</code> function creates a new IPP request:</p> |
| 1035 | <pre><code>ipp_t * |
| 1036 | ippNewRequest(ipp_op_t op); |
| 1037 | </code></pre> |
| 1038 | <p>The <code>op</code> argument specifies the IPP operation code for the request. For example, the following code creates an IPP Get-Printer-Attributes request:</p> |
| 1039 | <pre><code>ipp_t *request = ippNewRequest(IPP_OP_GET_PRINTER_ATTRIBUTES); |
| 1040 | </code></pre> |
| 1041 | <p>The request identifier is automatically set to a unique value for the current process.</p> |
| 1042 | <p>Each IPP request starts with two IPP attributes, "attributes-charset" and "attributes-natural-language", followed by IPP attribute(s) that specify the target of the operation. The <code>ippNewRequest</code> automatically adds the correct "attributes-charset" and "attributes-natural-language" attributes, but you must add the target attribute(s). For example, the following code adds the "printer-uri" attribute to the IPP Get-Printer-Attributes request to specify which printer is being queried:</p> |
| 1043 | <pre><code>const char *printer_uri = cupsGetOption("device-uri", |
| 1044 | dest->num_options, |
| 1045 | dest->options); |
| 1046 | |
| 1047 | ippAddString(request, IPP_TAG_OPERATION, IPP_TAG_URI, |
| 1048 | "printer-uri", NULL, printer_uri); |
| 1049 | </code></pre> |
| 1050 | <blockquote> |
| 1051 | <p><strong>Note:</strong></p> |
| 1052 | <p>If we wanted to query the scheduler instead of the device, we would look up the "printer-uri-supported" option instead of the "device-uri" value.</p> |
| 1053 | </blockquote> |
| 1054 | <p>The <code>ippAddString</code> function adds the "printer-uri" attribute the the IPP request. The <code>IPP_TAG_OPERATION</code> argument specifies that the attribute is part of the operation. The <code>IPP_TAG_URI</code> argument specifies that the value is a Universal Resource Identifier (URI) string. The <code>NULL</code> argument specifies there is no language (English, French, Japanese, etc.) associated with the string, and the <code>printer_uri</code> argument specifies the string value.</p> |
| 1055 | <p>The IPP Get-Printer-Attributes request also supports an IPP attribute called "requested-attributes" that lists the attributes and values you are interested in. For example, the following code requests the printer state attributes:</p> |
| 1056 | <pre><code>static const char * const requested_attributes[] = |
| 1057 | { |
| 1058 | "printer-state", |
| 1059 | "printer-state-message", |
| 1060 | "printer-state-reasons" |
| 1061 | }; |
| 1062 | |
| 1063 | ippAddStrings(request, IPP_TAG_OPERATION, IPP_TAG_KEYWORD, |
| 1064 | "requested-attributes", 3, NULL, |
| 1065 | requested_attributes); |
| 1066 | </code></pre> |
| 1067 | <p>The <code>ippAddStrings</code> function adds an attribute with one or more strings, in this case three. The <code>IPP_TAG_KEYWORD</code> argument specifies that the strings are keyword values, which are used for attribute names. All strings use the same language (<code>NULL</code>), and the attribute will contain the three strings in the array <code>requested_attributes</code>.</p> |
| 1068 | <p>CUPS provides many functions to adding attributes of different types:</p> |
| 1069 | <ul> |
| 1070 | <li><code>ippAddBoolean</code> adds a boolean (<code>IPP_TAG_BOOLEAN</code>) attribute with one value.</li> |
| 1071 | <li><code>ippAddInteger</code> adds an enum (<code>IPP_TAG_ENUM</code>) or integer (<code>IPP_TAG_INTEGER</code>) attribute with one value.</li> |
| 1072 | <li><code>ippAddIntegers</code> adds an enum or integer attribute with one or more values.</li> |
| 1073 | <li><code>ippAddOctetString</code> adds an octetString attribute with one value.</li> |
| 1074 | <li><code>ippAddOutOfBand</code> adds a admin-defined (<code>IPP_TAG_ADMINDEFINE</code>), default (<code>IPP_TAG_DEFAULT</code>), delete-attribute (<code>IPP_TAG_DELETEATTR</code>), no-value (<code>IPP_TAG_NOVALUE</code>), not-settable (<code>IPP_TAG_NOTSETTABLE</code>), unknown (<code>IPP_TAG_UNKNOWN</code>), or unsupported (<code>IPP_TAG_UNSUPPORTED_VALUE</code>) out-of-band attribute.</li> |
| 1075 | <li><code>ippAddRange</code> adds a rangeOfInteger attribute with one range.</li> |
| 1076 | <li><code>ippAddRanges</code> adds a rangeOfInteger attribute with one or more ranges.</li> |
| 1077 | <li><code>ippAddResolution</code> adds a resolution attribute with one resolution.</li> |
| 1078 | <li><code>ippAddResolutions</code> adds a resolution attribute with one or more resolutions.</li> |
| 1079 | <li><code>ippAddString</code> adds a charset (<code>IPP_TAG_CHARSET</code>), keyword (<code>IPP_TAG_KEYWORD</code>), mimeMediaType (<code>IPP_TAG_MIMETYPE</code>), name (<code>IPP_TAG_NAME</code> and <code>IPP_TAG_NAMELANG</code>), naturalLanguage (<code>IPP_TAG_NATURAL_LANGUAGE</code>), text (<code>IPP_TAG_TEXT</code> and <code>IPP_TAG_TEXTLANG</code>), uri (<code>IPP_TAG_URI</code>), or uriScheme (<code>IPP_TAG_URISCHEME</code>) attribute with one value.</li> |
| 1080 | <li><code>ippAddStrings</code> adds a charset, keyword, mimeMediaType, name, naturalLanguage, text, uri, or uriScheme attribute with one or more values.</li> |
| 1081 | </ul> |
| 1082 | <h3><a id="sending-the-ipp-request">Sending the IPP Request</a></h3> |
| 1083 | <p>Once you have created the IPP request, you can send it using the <code>cupsDoRequest</code> function. For example, the following code sends the IPP Get-Printer-Attributes request to the destination and saves the response:</p> |
| 1084 | <pre><code>ipp_t *response = cupsDoRequest(http, request, resource); |
| 1085 | </code></pre> |
| 1086 | <p>For requests like Send-Document that include a file, the <code>cupsDoFileRequest</code> function should be used:</p> |
| 1087 | <pre><code>ipp_t *response = cupsDoFileRequest(http, request, resource, |
| 1088 | filename); |
| 1089 | </code></pre> |
| 1090 | <p>Both <code>cupsDoRequest</code> and <code>cupsDoFileRequest</code> free the IPP request. If a valid IPP response is received, it is stored in a new IPP message (<code>ipp_t</code>) and returned to the caller. Otherwise <code>NULL</code> is returned.</p> |
| 1091 | <p>The status from the most recent request can be queried using the <code>cupsLastError</code> function, for example:</p> |
| 1092 | <pre><code>if (cupsLastError() >= IPP_STATUS_ERROR_BAD_REQUEST) |
| 1093 | { |
| 1094 | /* request failed */ |
| 1095 | } |
| 1096 | </code></pre> |
| 1097 | <p>A human-readable error message is also available using the <code>cupsLastErrorString</code> function:</p> |
| 1098 | <pre><code>if (cupsLastError() >= IPP_STATUS_ERROR_BAD_REQUEST) |
| 1099 | { |
| 1100 | /* request failed */ |
| 1101 | printf("Request failed: %s\n", cupsLastErrorString()); |
| 1102 | } |
| 1103 | </code></pre> |
| 1104 | <h3><a id="processing-the-ipp-response">Processing the IPP Response</a></h3> |
| 1105 | <p>Each response to an IPP request is also an IPP message (<code>ipp_t</code>) with its own IPP attributes (<code>ipp_attribute_t</code>) that includes a status code (<code>IPP_STATUS_OK</code>, <code>IPP_STATUS_ERROR_BAD_REQUEST</code>, etc.) and the corresponding 32-bit integer identifier from the request.</p> |
| 1106 | <p>For example, the following code finds the printer state attributes and prints their values:</p> |
| 1107 | <pre><code>ipp_attribute_t *attr; |
| 1108 | |
| 1109 | if ((attr = ippFindAttribute(response, "printer-state", |
| 1110 | IPP_TAG_ENUM)) != NULL) |
| 1111 | { |
| 1112 | printf("printer-state=%s\n", |
| 1113 | ippEnumString("printer-state", ippGetInteger(attr, 0))); |
| 1114 | } |
| 1115 | else |
| 1116 | puts("printer-state=unknown"); |
| 1117 | |
| 1118 | if ((attr = ippFindAttribute(response, "printer-state-message", |
| 1119 | IPP_TAG_TEXT)) != NULL) |
| 1120 | { |
| 1121 | printf("printer-state-message=\"%s\"\n", |
| 1122 | ippGetString(attr, 0, NULL))); |
| 1123 | } |
| 1124 | |
| 1125 | if ((attr = ippFindAttribute(response, "printer-state-reasons", |
| 1126 | IPP_TAG_KEYWORD)) != NULL) |
| 1127 | { |
| 1128 | int i, count = ippGetCount(attr); |
| 1129 | |
| 1130 | puts("printer-state-reasons="); |
| 1131 | for (i = 0; i < count; i ++) |
| 1132 | printf(" %s\n", ippGetString(attr, i, NULL))); |
| 1133 | } |
| 1134 | </code></pre> |
| 1135 | <p>The <code>ippGetCount</code> function returns the number of values in an attribute.</p> |
| 1136 | <p>The <code>ippGetInteger</code> and <code>ippGetString</code> functions return a single integer or string value from an attribute.</p> |
| 1137 | <p>The <code>ippEnumString</code> function converts a enum value to its keyword (string) equivalent.</p> |
| 1138 | <p>Once you are done using the IPP response message, free it using the <code>ippDelete</code> function:</p> |
| 1139 | <pre><code>ippDelete(response); |
| 1140 | </code></pre> |
| 1141 | <h3><a id="authentication">Authentication</a></h3> |
| 1142 | <p>CUPS normally handles authentication through the console. GUI applications should set a password callback using the <code>cupsSetPasswordCB2</code> function:</p> |
| 1143 | <pre><code>void |
| 1144 | cupsSetPasswordCB2(cups_password_cb2_t cb, void *user_data); |
| 1145 | </code></pre> |
| 1146 | <p>The password callback will be called when needed and is responsible for setting the current user name using <code>cupsSetUser</code> and returning a string:</p> |
| 1147 | <pre><code>const char * |
| 1148 | cups_password_cb2(const char *prompt, http_t *http, |
| 1149 | const char *method, const char *resource, |
| 1150 | void *user_data); |
| 1151 | </code></pre> |
| 1152 | <p>The <code>prompt</code> argument is a string from CUPS that should be displayed to the user.</p> |
| 1153 | <p>The <code>http</code> argument is the connection hosting the request that is being authenticated. The password callback can call the <code>httpGetField</code> and <code>httpGetSubField</code> functions to look for additional details concerning the authentication challenge.</p> |
| 1154 | <p>The <code>method</code> argument specifies the HTTP method used for the request and is typically "POST".</p> |
| 1155 | <p>The <code>resource</code> argument specifies the path used for the request.</p> |
| 1156 | <p>The <code>user_data</code> argument provides the user data pointer from the <code>cupsSetPasswordCB2</code> call.</p> |
