8187 * This function only gets called when printing a single PDF or PostScript
8188 * file using the Print-Job operation. It doesn't work for Create-Job +
8189 * Send-File, since the job attributes need to be set at job creation
8190 * time for banners to work. The embedded job ticket stuff is here
8191 * primarily to allow the Windows printer driver for CUPS to pass in JCL
8192 * options and IPP attributes which otherwise would be lost.
8193 *
8194 * The format of a job ticket is simple:
8195 *
8196 * %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8197 *
8198 * %cupsJobTicket: attr1=value1
8199 * %cupsJobTicket: attr2=value2
8200 * ...
8201 * %cupsJobTicket: attrN=valueN
8202 *
8203 * Job ticket lines must appear immediately after the first line that
8204 * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8205 * stops looking for job ticket info when it finds a line that does not begin
8206 * with "%cupsJobTicket:".
8207 *
8208 * The maximum length of a job ticket line, including the prefix, is
8209 * 255 characters to conform with the Adobe DSC.
8210 *
8211 * Read-only attributes are rejected with a notice to the error log in
8212 * case a malicious user tries anything. Since the job ticket is read
8213 * prior to attribute validation in print_job(), job ticket attributes
8214 * will go through the same validation as IPP attributes...
