25
26 <p>CUPS implements IPP/1.1 and the operations and attributes
27 defined in the "IPP: Job and Printer Set Operations", "IPP/1.1:
28 Output-bin Attribute Extension", and "IPP/1.1: finishings
29 'fold',' trim', and 'bale' attribute values extension"
30 specifications.</p>
31
32 <p>CUPS also provides 16 new operations and many new attributes
33 to support multiple IPP printers and printer classes on a single
34 host.</p>
35
36 <h3 class='title'><a name='IPP_URIS'>IPP URIs</a></h3>
37
38 <p>CUPS supports the "http", "https", and "ipp" schemes. The
39 following resource names are used:</p>
40
41 <dl>
42
43 <dt><tt>scheme://hostname:port/</tt></dt>
44
45 <dd>Can be used for all "get" operations and for server
46 subscriptions.</dd>
47
48 <dt><tt>scheme://hostname:port/admin/</tt></dt>
49
50 <dd>Used for all administrative operations.</dd>
51
52 <dt><tt>scheme://hostname:port/classes/name</tt></dt>
53
54 <dd>Specifies a printer class.</dd>
55
56 <dt><tt>scheme://hostname:port/jobs/id</tt></dt>
57
58 <dd>Specifies a job.</dd>
59
60 <dt><tt>scheme://hostname:port/printers/name</tt></dt>
61
62 <dd>Specifies a printer.</dd>
63
64 </dl>
65
66 <p>So a typical printer URI would be
67 "ipp://foo.bar.com/printers/LaserJet". In addition, the CUPS
68 server also supports normal browser access via
69 "http://hostname:port/" and "https://hostname:port/".</p>
70
71 <h3 class='title'><a name='IPP_OPERATIONS'>CUPS IPP Operations</a></h3>
72
73 <p>CUPS provides 16 extension operations in addition to most of the
74 standard IPP and registered extension operations:

2044
2045 <h4><a name="device-class">device-class (type2 keyword)</a></h4>
2046
2047 <p>The device-class attribute specifies the class of device and can be
2048 one of the following:
2049
2050 <ul>
2051
2052 <li>"file" - a disk file.
2053
2054 <li>"direct" - a parallel or fixed-rate serial data port,
2055 currently used for Centronics, IEEE-1284, and USB printer
2056 ports.
2057
2058 <li>"serial" - a variable-rate serial port.
2059
2060 <li>"network" - a network connection, typically via AppSocket,

2066
2067 <p>The device-id attribute specifies the IEEE-1284 device ID
2068 string for the device.</p>
2069
2070 <h4><a name="device-info">device-info (text(127))</a></h4>
2071
2072 <p>The device-info attribute specifies a human-readable string describing

2081
2082 <p>The device-make-and-model attribute specifies a device
2083 identification string provided by the printer connected to the device.
2084 If the device or printer does not support identification then this

2086
2087 <h4><a name="device-uri">device-uri (uri)</a></h4>
2088
2089 <p>The device-uri attribute specifies a unique identifier for the
2090 device. The actual format of the device-uri string depends on the value
2091 of the device-class attribute:
2092
2093 <ul>
2094
2095 <li>"file" - The device-uri will be of the form
2096 "file:///path/to/filename".
2097
2098 <li>"direct" - The device-uri will be of the form
2099 "scheme:/dev/filename" or "scheme://vendor/identifier",
2100 where scheme may be "parallel" or "usb" in the current
2101 implementation.
2102
2103 <li>"serial" - The device-uri will be of the form
2104 "serial:/dev/filename?baud=value+parity=value+flow=value".
2105 The baud value is the data rate in bits per second; the
2106 supported values depend on the underlying hardware.
2107 The parity value can be one of "none", "even", or "odd".
2108 The flow value can be one of "none", "soft" (XON/XOFF
2109 handshaking), "hard" or "rts/cts" (RTS/CTS handshaking),
2110 or "dtrdsr" (DTR/DSR handshaking).
2111
2112 <p>The URI returned by CUPS-Get-Devices will contain the
2113 maximum baud rate supported by the device and the best
2114 type of flow control available ("soft" or "hard").
2115
2116 <li>"network" - The device-uri will be of the form
2117 "scheme://[username:password@]hostname[:port]/[resource]",
2118 where scheme may be "http", "https", "ipp", "lpd", "smb", or
2119 "socket" in the current implementation.
2120
2121 <p>The URI returned by CUPS-Get-Devices will only contain
2122 the scheme name ("scheme"). It is up to the client
2123 application to add the appropriate host and other
2124 information when adding a new printer.
2125
2126 <p>The URI returned by Get-Printer-Attributes and
2127 CUPS-Get-Printers has any username and password information
2128 stripped; the information is still stored and used by the
2129 server internally to perform any needed authentication.

2831 <p>The printer-type-mask attribute is used to choose printers or classes with
2832 the CUPS-Get-Printers and CUPS-Get-Classes operations. The bits are defined
2833 identically to the printer-type attribute and default to all 1's.

2836
2837 <p>The requesting-user-name-allowed attribute lists all of the users that are
2838 allowed to access a printer or class. Either this attribute or the
2839 requesting-user-name-denied attribute will be defined, but not both.

2855 <h4>member-uris (1setof uri)</h4>
2856
2857 <p>The member-uris attribute specifies each of the printer-uri attributes of
