6917 * specifies PostScript format (%!PS-Adobe-3.0), and CUPS will stop
6918 * looking for job ticket info when it finds a line that does not begin
6919 * with "%cupsJobTicket:".

6924 * Read-only attributes are rejected with a notice to the error log in
6925 * case a malicious user tries anything. Since the job ticket is read
