8261 * Send-File, since the job attributes need to be set at job creation
8262 * time for banners to work. The embedded job ticket stuff is here
8263 * primarily to allow the Windows printer driver for CUPS to pass in JCL
8264 * options and IPP attributes which otherwise would be lost.
8265 *
8266 * The format of a job ticket is simple:
8267 *
8268 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8269 *
8270 * %cupsJobTicket: attr1=value1
8271 * %cupsJobTicket: attr2=value2
8272 * ...
8273 * %cupsJobTicket: attrN=valueN
8274 *
8275 * Job ticket lines must appear immediately after the first line that
8276 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8277 * stops looking for job ticket info when it finds a line that does not begin
8278 * with "%cupsJobTicket:".
8279 *
8280 * The maximum length of a job ticket line, including the prefix, is
8281 * 255 characters to conform with the Adobe DSC.
8282 *
8283 * Read-only attributes are rejected with a notice to the error log in
8284 * case a malicious user tries anything. Since the job ticket is read
8285 * prior to attribute validation in print_job(), job ticket attributes
8286 * will go through the same validation as IPP attributes...
