pdfSetPrintEmulatedMultiCopy

Enable/disable emulated multi copy mode for printing.
void pdfSetPrintEmulatedMultiCopy(PDFViewerHandle viewer, BOOL emulated)
By default, the number of copies requested in a pdfPrint3 or pdfStartPrintJob call is passed to the printer driver. But not all printers/drivers support printing multiple copies and/or collation. The pdfSetPrintEmulatedMultiCopy function can be used to enable "emulated multi copy" mode, in which XpdfViewer will generate a print stream with multiple copies (as specified by the nCopies argument to pdfPrint3 or pdfStartPrintJob) of each page, in collated order.

The advantage of emulated multi copy mode is that it will work on all printers. The disadvantage is that the spool file will be larger (because it contains multiple copies of each page).

Calling pdfPrintSetEmulatedMultiCopy with a true emulated argument enables emulated multi copy mode. Calling with a false emulated argument disables it.

This setting only affects the pdfPrint3 and pdfStartPrintJob functions.
