8673 * Send-File, since the job attributes need to be set at job creation
8674 * time for banners to work. The embedded job ticket stuff is here
8675 * primarily to allow the Windows printer driver for CUPS to pass in JCL
8676 * options and IPP attributes which otherwise would be lost.
8677 *
8678 * The format of a job ticket is simple:
8679 *
8680 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8681 *
8682 * %cupsJobTicket: attr1=value1
8683 * %cupsJobTicket: attr2=value2
8684 * ...
8685 * %cupsJobTicket: attrN=valueN
8686 *
8687 * Job ticket lines must appear immediately after the first line that
8688 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8689 * stops looking for job ticket info when it finds a line that does not begin
8690 * with "%cupsJobTicket:".
8691 *
8692 * The maximum length of a job ticket line, including the prefix, is
8693 * 255 characters to conform with the Adobe DSC.
8694 *
8695 * Read-only attributes are rejected with a notice to the error log in
8696 * case a malicious user tries anything. Since the job ticket is read
8697 * prior to attribute validation in print_job(), job ticket attributes
8698 * will go through the same validation as IPP attributes...
