7770 * specifies PostScript format (%!PS-Adobe-3.0), and CUPS will stop
7771 * looking for job ticket info when it finds a line that does not begin
7772 * with "%cupsJobTicket:".
7773 *
7774 * The maximum length of a job ticket line, including the prefix, is
7775 * 255 characters to conform with the Adobe DSC.
7776 *
7777 * Read-only attributes are rejected with a notice to the error log in
7778 * case a malicious user tries anything. Since the job ticket is read
7779 * prior to attribute validation in print_job(), job ticket attributes
7780 * will go through the same validation as IPP attributes...
