* only to allow the Windows printer driver for CUPS to pass in JCL
* options and IPP attributes which otherwise would be lost.

*
* %cupsJobTicket: attr1=value1
* %cupsJobTicket: attr2=value2
* ...
* %cupsJobTicket: attrN=valueN
*
* Job ticket lines must appear immediately after the first line that
* specifies PostScript format (%!PS-Adobe-3.0), and CUPS will stop
* looking for job ticket info when it finds a line that does not begin
* with "%cupsJobTicket:".
*
* The maximum length of a job ticket line, including the prefix, is
* 255 characters to conform with the Adobe DSC.
*
* Read-only attributes are rejected with a notice to the error log in
* case a malicious user tries anything. Since the job ticket is read
* prior to attribute validation in print_job(), job ticket attributes
* will go through the same validation as IPP attributes...
