pdfPrintForceMono
Force printing in monochrome.
void pdfPrintForceMono(PDFHandle pdf, int mono)
If this function is called with
mono
= 1, XpdfPrint
generates monochrome output, even if the printer appears to be color.
This setting is only relevant for GDI printing, i.e., for
non-PostScript printers, or if pdfPrintForceGDI
is in effect. It
is ignored when XpdfPrint generates PostScript code.
pdfPrintResetParams
resets this to its default value of 0, which
means to generate monochrome output for monochrome printers and color
output for color printers.
