8620 * This function only gets called when printing a single PDF or PostScript
8621 * file using the Print-Job operation. It doesn't work for Create-Job +
8622 * Send-File, since the job attributes need to be set at job creation
8623 * time for banners to work. The embedded job ticket stuff is here
8624 * primarily to allow the Windows printer driver for CUPS to pass in JCL
8625 * options and IPP attributes which otherwise would be lost.
8626 *
8627 * The format of a job ticket is simple:
8628 *
8629 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8630 *
8631 * %cupsJobTicket: attr1=value1
8632 * %cupsJobTicket: attr2=value2
8633 * ...
8634 * %cupsJobTicket: attrN=valueN
8635 *
8636 * Job ticket lines must appear immediately after the first line that
8637 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8638 * stops looking for job ticket info when it finds a line that does not begin
8639 * with "%cupsJobTicket:".
8640 *
8641 * The maximum length of a job ticket line, including the prefix, is
8642 * 255 characters to conform with the Adobe DSC.
8643 *
8644 * Read-only attributes are rejected with a notice to the error log in
8645 * case a malicious user tries anything. Since the job ticket is read
8646 * prior to attribute validation in print_job(), job ticket attributes
8647 * will go through the same validation as IPP attributes...
