8662 * Send-File, since the job attributes need to be set at job creation
8663 * time for banners to work. The embedded job ticket stuff is here
8664 * primarily to allow the Windows printer driver for CUPS to pass in JCL
8665 * options and IPP attributes which otherwise would be lost.
8666 *
8667 * The format of a job ticket is simple:
8668 *
8669 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8670 *
8671 * %cupsJobTicket: attr1=value1
8672 * %cupsJobTicket: attr2=value2
8673 * ...
8674 * %cupsJobTicket: attrN=valueN
8675 *
8676 * Job ticket lines must appear immediately after the first line that
8677 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8678 * stops looking for job ticket info when it finds a line that does not begin
8679 * with "%cupsJobTicket:".
8680 *
8681 * The maximum length of a job ticket line, including the prefix, is
8682 * 255 characters to conform with the Adobe DSC.
8683 *
8684 * Read-only attributes are rejected with a notice to the error log in
8685 * case a malicious user tries anything. Since the job ticket is read
8686 * prior to attribute validation in print_job(), job ticket attributes
8687 * will go through the same validation as IPP attributes...
