So far we use the "ghostpdf.inf" from the Ghostscript program directory as PDF printer "Sybase DataWindow PS".
But this driver is not signed and the installation under Windows 8.1 is not possible.
Which driver should we use for Windows 8.1? Does anyone have a recommendation for us?
Does anyone know any advantages or disadvantages of ghostscript 64-bit vs ghostscript 32-bit?
PS: Disable Driver Signature Verification in Windows 8.1 is not a solution for us.
