8282 * time for banners to work. The embedded job ticket stuff is here
8283 * primarily to allow the Windows printer driver for CUPS to pass in JCL
8284 * options and IPP attributes which otherwise would be lost.
8285 *
8286 * The format of a job ticket is simple:
8287 *
8288 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8289 *
8290 * %cupsJobTicket: attr1=value1
8291 * %cupsJobTicket: attr2=value2
8292 * ...
8293 * %cupsJobTicket: attrN=valueN
8294 *
8295 * Job ticket lines must appear immediately after the first line that
8296 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8297 * stops looking for job ticket info when it finds a line that does not begin
8298 * with "%cupsJobTicket:".
8299 *
8300 * The maximum length of a job ticket line, including the prefix, is
8301 * 255 characters to conform with the Adobe DSC.
8302 *
8303 * Read-only attributes are rejected with a notice to the error log in
8304 * case a malicious user tries anything. Since the job ticket is read
8305 * prior to attribute validation in print_job(), job ticket attributes
8306 * will go through the same validation as IPP attributes...
