8295 * options and IPP attributes which otherwise would be lost.
8296 *
8297 * The format of a job ticket is simple:
8298 *
8299 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8300 *
8301 * %cupsJobTicket: attr1=value1
8302 * %cupsJobTicket: attr2=value2
8303 * ...
8304 * %cupsJobTicket: attrN=valueN
8305 *
8306 * Job ticket lines must appear immediately after the first line that
8307 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8308 * stops looking for job ticket info when it finds a line that does not begin
8309 * with "%cupsJobTicket:".
8310 *
8311 * The maximum length of a job ticket line, including the prefix, is
8312 * 255 characters to conform with the Adobe DSC.
8313 *
8314 * Read-only attributes are rejected with a notice to the error log in
8315 * case a malicious user tries anything. Since the job ticket is read
8316 * prior to attribute validation in print_job(), job ticket attributes
8317 * will go through the same validation as IPP attributes...
