6935 * options and IPP attributes which otherwise would be lost.
6936 *

6938 *
6939 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
6940 *
6941 * %cupsJobTicket: attr1=value1
6942 * %cupsJobTicket: attr2=value2
6943 * ...

6945 *
6946 * Job ticket lines must appear immediately after the first line that
6947 * specifies PostScript format (%!PS-Adobe-3.0), and CUPS will stop
6948 * looking for job ticket info when it finds a line that does not begin
6949 * with "%cupsJobTicket:".
6950 *
6951 * The maximum length of a job ticket line, including the prefix, is
6952 * 255 characters to conform with the Adobe DSC.
6953 *
6954 * Read-only attributes are rejected with a notice to the error log in
6955 * case a malicious user tries anything. Since the job ticket is read
6956 * prior to attribute validation in print_job(), job ticket attributes
6957 * will go through the same validation as IPP attributes...
