6870 * This function only gets called when printing a single PostScript

6872 * Send-File, since the job attributes need to be set at job creation
6873 * time for banners to work. The embedded PS job ticket stuff is here
6874 * only to allow the Windows printer driver for CUPS to pass in JCL
6875 * options and IPP attributes which otherwise would be lost.
6876 *
6877 * The format of a PS job ticket is simple:
6878 *
6879 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
6880 *
6881 * %cupsJobTicket: attr1=value1
6882 * %cupsJobTicket: attr2=value2
6883 * ...
6884 * %cupsJobTicket: attrN=valueN
6885 *
6886 * Job ticket lines must appear immediately after the first line that
6887 * specifies PostScript format (%!PS-Adobe-3.0), and CUPS will stop
6888 * looking for job ticket info when it finds a line that does not begin
6889 * with "%cupsJobTicket:".
6890 *
6891 * The maximum length of a job ticket line, including the prefix, is
6892 * 255 characters to conform with the Adobe DSC.
6893 *
6894 * Read-only attributes are rejected with a notice to the error log in
6895 * case a malicious user tries anything. Since the job ticket is read
6896 * prior to attribute validation in print_job(), job ticket attributes
6897 * will go through the same validation as IPP attributes...
