8650 * This function only gets called when printing a single PDF or PostScript
8651 * file using the Print-Job operation. It doesn't work for Create-Job +
8652 * Send-File, since the job attributes need to be set at job creation
8653 * time for banners to work. The embedded job ticket stuff is here
8654 * primarily to allow the Windows printer driver for CUPS to pass in JCL
8655 * options and IPP attributes which otherwise would be lost.
8656 *
8657 * The format of a job ticket is simple:
8658 *
8659 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8660 *
8661 * %cupsJobTicket: attr1=value1
8662 * %cupsJobTicket: attr2=value2
8663 * ...
8664 * %cupsJobTicket: attrN=valueN
8665 *
8666 * Job ticket lines must appear immediately after the first line that
8667 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8668 * stops looking for job ticket info when it finds a line that does not begin
8669 * with "%cupsJobTicket:".
8670 *
8671 * The maximum length of a job ticket line, including the prefix, is
8672 * 255 characters to conform with the Adobe DSC.
8673 *
8674 * Read-only attributes are rejected with a notice to the error log in
8675 * case a malicious user tries anything. Since the job ticket is read
8676 * prior to attribute validation in print_job(), job ticket attributes
8677 * will go through the same validation as IPP attributes...
