forceImage

Force printing each page as an image.
[read/write property] forceImage([out, retval] VARIANT_BOOL *image) forceImage([in] VARIANT_BOOL image)
If this property is set to true, all pages will be rasterized, and sent to the printer as images.

This setting is only relevant for GDI printing, i.e., for non-PostScript printers, or if forceGDI is true. It is ignored when XpdfPrint generates PostScript code.

resetParams resets this to its default value of false, which means to optimize by using GDI operations where possible.

VB:
pdf.forceImage = True
resetParams
