7754 * specifies PostScript format (%!PS-Adobe-3.0), and CUPS will stop
7755 * looking for job ticket info when it finds a line that does not begin
7756 * with "%cupsJobTicket:".
7757 *
7758 * The maximum length of a job ticket line, including the prefix, is
7759 * 255 characters to conform with the Adobe DSC.
7760 *
7761 * Read-only attributes are rejected with a notice to the error log in
7762 * case a malicious user tries anything. Since the job ticket is read
7763 * prior to attribute validation in print_job(), job ticket attributes
7764 * will go through the same validation as IPP attributes...
