Get the job ID for the most recent print job.
int pdfGetJobID(PDFHandle pdf)
This function returns the print job ID corresponding to the most recent call to pdfPrint4. This value can be passed to the Windows GetJob and SetJob functions to query and manipulate the print job.

(The pdfPrintToDC2 function does not create a print job. The caller is responsible for calling StartDoc, and pdfGetJobID will not return a useful value in that situation.)

int jobID = pdfGetJobID(pdf);
