8694 * stops looking for job ticket info when it finds a line that does not begin
8695 * with "%cupsJobTicket:".
8696 *
8697 * The maximum length of a job ticket line, including the prefix, is
8698 * 255 characters to conform with the Adobe DSC.
8699 *
8700 * Read-only attributes are rejected with a notice to the error log in
8701 * case a malicious user tries anything. Since the job ticket is read
