This all works flawlessly if you use the right version of GhostScript.
For Win8.1, use the Ghostscript Download at www.ghostscript.com/downlo0ad/gsdnld.html
This driver has been digitally signed, so no need to go through the unsigned driver install process.
I tested this with PB 12.6, Win 8.1 (64 bit), and Ghostscript 9.19 for Windows (64 bit)
