8681 * Send-File, since the job attributes need to be set at job creation
8682 * time for banners to work. The embedded job ticket stuff is here
8683 * primarily to allow the Windows printer driver for CUPS to pass in JCL
8684 * options and IPP attributes which otherwise would be lost.
8685 *
8686 * The format of a job ticket is simple:
8687 *
8688 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8689 *
8690 * %cupsJobTicket: attr1=value1
8691 * %cupsJobTicket: attr2=value2
8692 * ...
8693 * %cupsJobTicket: attrN=valueN
8694 *
8695 * Job ticket lines must appear immediately after the first line that
8696 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8697 * stops looking for job ticket info when it finds a line that does not begin
8698 * with "%cupsJobTicket:".
8699 *
8700 * The maximum length of a job ticket line, including the prefix, is
8701 * 255 characters to conform with the Adobe DSC.
8702 *
8703 * Read-only attributes are rejected with a notice to the error log in
8704 * case a malicious user tries anything. Since the job ticket is read
8705 * prior to attribute validation in print_job(), job ticket attributes
8706 * will go through the same validation as IPP attributes...
