26 | <h2 class='title'><a name='INTRODUCTION'>Introduction</a></h2> | |
27 | ||
28 | <p>This specification describes the CUPS command file format | |
29 | (application/vnd.cups-command) which is used to send printer | |
30 | maintenance commands to a printer in a device-independent way. | |
31 | The current specification supports basic maintenance functions | |
32 | such as head cleaning and self-test pages.</p> | |
33 | ||
34 | <p>Printer drivers advertise support for the CUPS command file | |
35 | format by providing a filter for the | |
36 | <var>application/vnd.cups-command</var> file type. Applications | |
37 | can determine if a printer supports printing of CUPS command | |
38 | files by checking the <code>printer-type</code> attribute for the | |
39 | <code>CUPS_PRINTER_COMMANDS</code> capability bit.</p> | |
40 | ||
01ce6322 MS |
41 | <p>In addition, the PPD file for a printer can contain a |
42 | <code>cupsCommands</code> keyword that provides a list of supported | |
43 | commands separated by spaces, for example:</p> | |
44 | ||
45 | <pre class='command'> | |
46 | *cupsCommand: "AutoConfigure Clean PrintSelfTestPage ReportLevels" | |
47 | </pre> | |
48 | ||
49 | <p>If no <code>cupsCommands</code> keyword is provided, the command filter | |
50 | must support <a href='#AutoConfigure'><code>AutoConfigure</code></a>, | |
51 | <a href='#Clean'><code>Clean</code></a>, | |
52 | <a href='#PrintSelfTestPage'><code>PrintSelfTestPage</code></a>, | |
53 | and <a href='#ReportLevels'><code>ReportLevels</code></a>. The scheduler also | |
54 | provides the <code>printer-commands</code> attribute containing the list of | |
55 | supported commands.</p> | |
56 | ||
57 | ||
b423cd4c | 58 | <h2 class='title'><a name='SYNTAX'>File Syntax</a></h2> |
59 | ||
60 | <p>CUPS command files are ASCII text files. The first line of a | |
61 | CUPS command file MUST contain:</p> | |
62 | ||
63 | <pre class='command'> | |
64 | #CUPS-COMMAND | |
65 | </pre> | |
66 | ||
67 | <p>After that, each line is either a command or a comment. | |
68 | Comments begin with the # character, e.g.:</p> | |
69 | ||
70 | <pre class='command'> | |
71 | # This is a comment | |
72 | </pre> | |
73 | ||
01ce6322 MS |
74 | <p>Commands are any sequence of letters, numbers, and punctuation characters |
75 | optionally followed by parameters separated by whitespace, e.g.:</p> | |
76 | ||
77 | <pre class='command'> | |
78 | Clean all | |
79 | PrintSelfTestPage | |
80 | </pre> | |
81 | ||
82 | <p>Command names are case-insensitive, so "PRINTSELFTESTPAGE", | |
83 | "printselftestpage", and "PrintSelfTestPage" are equivalent. Vendor-specific | |
84 | commands should use a domain name prefix, e.g.:</p> | |
85 | ||
86 | <pre class='command'> | |
87 | com.vendor.foo | |
88 | com.vendor.bar param param2 ... paramN | |
89 | </pre> | |

94 | <p>The following are the standard commands supported by the format. The only |
95 | required command is | |
96 | <a href='#PrintSelfTestPage'><code>PrintSelfTestPage</code></a>.</p> | |

01ce6322 MS |
101 | <p class='summary'>AutoConfigure</p> |
102 | ||
103 | <p>The <code>AutoConfigure</code> command updates the printer's PPD file | |
104 | and driver state information to reflect the current configuration of the | |
105 | printer. There are no arguments for this command.</p> | |
106 | ||
107 | <p>Example:</p> | |
108 | ||
109 | <pre class='command'> | |
110 | #CUPS-COMMAND | |
111 | AutoConfigure | |
112 | </pre> | |
113 | ||
114 | ||
115 | <h3><a name='Clean'>Clean</a></h3> | |
116 | ||
117 | <p class='summary'>Clean <i>colorname</i></p> | |
118 | ||
119 | <p>The <code>Clean</code> command performs a standard print head cleaning. The | |
120 | "colorname" parameter specifies which color or head to clean. If a printer does | |
121 | not support cleaning of individual colors or cartridges, then all colors are | |
122 | cleaned. Command filters MUST support the "all" colorname. Other standard color | |
123 | names include "black", "color", "photo", "cyan", "magenta", "yellow", | |
124 | "light-cyan", "light-magenta", "light-black", "light-gray", and "dark-gray".</p> | |
b423cd4c | 125 | |
126 | <p>Example:</p> | |
127 | ||
128 | <pre class='command'> | |
129 | #CUPS-COMMAND | |
130 | Clean all | |

134 | <h3><a name='PrintAlignmentPage'>PrintAlignmentPage</a></h3> | |
135 | ||
136 | <p class='summary'>PrintAlignmentPage pass</p> | |
137 | ||
138 | <p>The <code>PrintAlignmentPage</code> command prints a head alignment page on | |
139 | the printer. The "pass" parameter provides a pass number from 1 to N. The number | |
140 | of passes is device-dependent.</p> | |
141 | ||
142 | <p>Example:</p> | |
143 | ||
144 | <pre class='command'> | |
145 | #CUPS-COMMAND | |
146 | PrintAlignmentPage 1 | |
147 | </pre> | |

152 | <p class='summary'>PrintSelfTestPage</p> | |
153 | ||
01ce6322 MS |
154 | <p>The <code>PrintSelfTestPage</code> command prints a self-test page on the |
155 | printer. Typically this page shows whether all jets on a print head are | |
156 | functioning and that the print feed mechanisms are working properly.</p> | |
b423cd4c | 157 | |
158 | <p>Example:</p> | |
159 | ||
160 | <pre class='command'> | |
161 | #CUPS-COMMAND | |
162 | PrintSelfTestPage | |
163 | </pre> | |

166 | <h3><a name='ReportLevels'>ReportLevels</a></h3> | |
167 | ||
168 | <p class='summary'>ReportLevels</p> | |
169 | ||
170 | <p>The <code>ReportLevels</code> command queries the supply levels on a printer | |
171 | and reports "marker-colors", "marker-levels", "marker-names", and | |
172 | "marker-types" attributes using "ATTR:" messages sent to the scheduler.</p> | |
173 | ||
174 | <p>Example:</p> | |
175 | ||
176 | <pre class='command'> | |
177 | #CUPS-COMMAND | |
178 | ReportLevels | |
179 | </pre> | |

181 | ||
182 | <h3><a name='SetAlignment'>SetAlignment</a></h3> | |
183 | ||
184 | <p class='summary'>SetAlignment pass value ... valueN</p> | |
185 | ||
186 | <p>The <code>SetAlignment</code> command sets print head alignment values. The | |
187 | "pass" parameter is a number from 1 to N. All parameters are | |
188 | device-dependent.</p> | |
189 | ||
190 | <p>Example:</p> | |
191 | ||
192 | <pre class='command'> | |
193 | #CUPS-COMMAND | |
194 | SetAlignment 1 14 | |
195 | </pre> | |
