Force the print operation to go through GDI.
void pdfSetPrintForceGDI(PDFViewerHandle viewer, BOOL gdi)
If this function is called with gdi = true, all printing will go through Windows GDI, even for PostScript printers. If gdi = false (the default value), XpdfViewer will generate its own PostScript code for PostScript printers and use GDI for other printers.
pdfSetPrintForceGDI(pdf, TRUE);
