8623 * This function only gets called when printing a single PDF or PostScript
8624 * file using the Print-Job operation. It doesn't work for Create-Job +
8625 * Send-File, since the job attributes need to be set at job creation
8626 * time for banners to work. The embedded job ticket stuff is here
8627 * primarily to allow the Windows printer driver for CUPS to pass in JCL
8628 * options and IPP attributes which otherwise would be lost.
8629 *
8630 * The format of a job ticket is simple:
8631 *
8632 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8633 *
8634 * %cupsJobTicket: attr1=value1
8635 * %cupsJobTicket: attr2=value2
8636 * ...
8637 * %cupsJobTicket: attrN=valueN
8638 *
8639 * Job ticket lines must appear immediately after the first line that
8640 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8641 * stops looking for job ticket info when it finds a line that does not begin
8642 * with "%cupsJobTicket:".
8643 *
8644 * The maximum length of a job ticket line, including the prefix, is
8645 * 255 characters to conform with the Adobe DSC.
8646 *
8647 * Read-only attributes are rejected with a notice to the error log in
8648 * case a malicious user tries anything. Since the job ticket is read
8649 * prior to attribute validation in print_job(), job ticket attributes
8650 * will go through the same validation as IPP attributes...
