6930 * Send-File, since the job attributes need to be set at job creation

6933 * options and IPP attributes which otherwise would be lost.
6934 *
6935 * The format of a PS job ticket is simple:
6936 *
6937 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
6938 *
6939 * %cupsJobTicket: attr1=value1
6940 * %cupsJobTicket: attr2=value2
6941 * ...
6942 * %cupsJobTicket: attrN=valueN
6943 *
6944 * Job ticket lines must appear immediately after the first line that
6945 * specifies PostScript format (%!PS-Adobe-3.0), and CUPS will stop
6946 * looking for job ticket info when it finds a line that does not begin
6947 * with "%cupsJobTicket:".
6948 *
6949 * The maximum length of a job ticket line, including the prefix, is
6950 * 255 characters to conform with the Adobe DSC.
6951 *
6952 * Read-only attributes are rejected with a notice to the error log in
6953 * case a malicious user tries anything. Since the job ticket is read
6954 * prior to attribute validation in print_job(), job ticket attributes
6955 * will go through the same validation as IPP attributes...
