pdfPrintForceGDI

Force the print operation to go through GDI.
void pdfPrintForceGDI(PDFHandle pdf, int gdi)
If this function is called with gdi = 1, all printing will go through Windows GDI, even for PostScript printers.

pdfPrintResetParams resets this to its default value of 0, which means to generate PostScript code for PostScript printers, and use GDI for non-PostScript printers.
