Now it seems to work with ghostscript 9.18-5 installed from ANPM. I just wrote it down here to don't forget about it next year.

PMPDF was not working for me as I believe the documents I was printing were relying on fonts that were not available with the current ghostscript (v9.18-7) installed via ANPM.
I initially elected to manually install the prior version of ghostscript (v8.71) via a zip file and point PMPDF to this directory tree, as you describe in your tutorial. This required that I uninstall v9 ghostscript without impacting CUPS which I use. I used the "--nodeps" option to do this...
rpm -qa | grep "ghostscript"
ghostscript-fonts-6.0-1.oc00.noarch
ghostscript-9.18-7.oc00.i686
rpm -e --nodeps "ghostscript-9.18-7.oc00.i686"
rpm -e --nodeps "ghostscript-fonts-6.0-1.oc00.noarch"
After getting this running, I decided it would be better to keep v.9 ghostscript in case it was needed for something in the future, but only use the Fonts from the older v.8 ghostscript. So, I reinstalled v.9 ghostscript and copied the fonts directory from v.8 moving it under the v.9 ghostscript directory tree. I then passed the v.8 fonts directory location to PMPDF using the "Extra parameters to GhostScript" option in the PDF output port. The override option I used was:
-lc:/@unixroot/usr/share/ghostscript/9.18/Resource/Font;c:/PSFONTS
See the attached screenshot for the location of the override.
So you can use either v.8 ghostscript without v9 ghostscript installed, or you can use v9 ghostscript with the added v.8 fonts directory and PMPDF override.
