pdfPrinterSupportsPostScriptW
Check to see if a printer supports PostScript (Unicode).
int pdfPrinterSupportsPostScriptW(wchar_t *printerName)
This function returns non-zero if the specified printer supports
PostScript.
pdfPrinterSupportsPostScriptW checks whether XpdfPrint
will (by default) use its internal PostScript generation path for this
printer. A few PostScript printer drivers are not supported by
XpdfPrint – this function returns zero in those cases.
When pdfPrinterSupportsPostScriptW returns true, the
pdfPrintForceGDI function can be used to force XpdfPrint to use
its GDI printing path.

if (pdfPrinterSupportsPostScriptW(printerName)) {
