8664 * Send-File, since the job attributes need to be set at job creation
8665 * time for banners to work. The embedded job ticket stuff is here
8666 * primarily to allow the Windows printer driver for CUPS to pass in JCL
8667 * options and IPP attributes which otherwise would be lost.
8668 *
8669 * The format of a job ticket is simple:
8670 *
8671 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8672 *
8673 * %cupsJobTicket: attr1=value1
8674 * %cupsJobTicket: attr2=value2
8675 * ...
8676 * %cupsJobTicket: attrN=valueN
8677 *
8678 * Job ticket lines must appear immediately after the first line that
8679 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8680 * stops looking for job ticket info when it finds a line that does not begin
8681 * with "%cupsJobTicket:".
8682 *
8683 * The maximum length of a job ticket line, including the prefix, is
8684 * 255 characters to conform with the Adobe DSC.
8685 *
8686 * Read-only attributes are rejected with a notice to the error log in
8687 * case a malicious user tries anything. Since the job ticket is read
8688 * prior to attribute validation in print_job(), job ticket attributes
8689 * will go through the same validation as IPP attributes...
