8565 * This function only gets called when printing a single PDF or PostScript
8566 * file using the Print-Job operation. It doesn't work for Create-Job +
8567 * Send-File, since the job attributes need to be set at job creation
8568 * time for banners to work. The embedded job ticket stuff is here
8569 * primarily to allow the Windows printer driver for CUPS to pass in JCL
8570 * options and IPP attributes which otherwise would be lost.
8571 *
8572 * The format of a job ticket is simple:
8573 *
8574 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8575 *
8576 * %cupsJobTicket: attr1=value1
8577 * %cupsJobTicket: attr2=value2
8578 * ...
8579 * %cupsJobTicket: attrN=valueN
8580 *
8581 * Job ticket lines must appear immediately after the first line that
8582 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8583 * stops looking for job ticket info when it finds a line that does not begin
8584 * with "%cupsJobTicket:".
8585 *
8586 * The maximum length of a job ticket line, including the prefix, is
8587 * 255 characters to conform with the Adobe DSC.
8588 *
8589 * Read-only attributes are rejected with a notice to the error log in
8590 * case a malicious user tries anything. Since the job ticket is read
8591 * prior to attribute validation in print_job(), job ticket attributes
8592 * will go through the same validation as IPP attributes...
