GhostScript Resolution of postscript file

I require some assistance with ghostscript.

Regardless what I have tried, the output from the ghostscript virtual printer has resolution 720dpi. Does anybody know how to increase that? I have tried changing the “print quality” in the advanced options of the preferences but that had no affect.

Also, are there any active user forums for ghostscript?


not sure if it helps, but just in case you haven’t come across it yet :

Best regards
