Adding Fonts to Ghostscript

Symptom: Some of my VFP reports produce a blank page when I run them through the Bullzip/Ghostscript pdf converter. After much research I am confident that the problem is down to the fonts I'm using in the report. But we're not talking obscure fonts here. One of the problem fonts is "Times New Roman", so I'm not about to tell my users to switch fonts. Clearly we need to tell Ghostscript how to find the fonts we want to use.

The documentation available on the web is contradictory and confusing.

Do we need a fontmap or not with version 8.64 of Bullzip (or version 8.70 of ghostscript which I've also installed in an attempt to troubleshoot the problem)

If so what exactly do we call it ("fontmap" or "fontmap.gs") and where do we put it?

do we need to use tools like ttfpt1.exe to convert the relevant fonts to ps fonts first?

do we need to set environtmental variables like GS_FONTPATH in order for Ghostscript to be able to find the fonts?

if so, where do we set such variables, in the windows environment or one of the gs###.ps files and if the latter, which one?

and so on. The more I read the more confusing it all gets.

If anyone can provide an authoritative idiot guide to "How to make Ghostscript Accept Windows Fonts" I'd happily award you 5000 points. Unfortunately the rules limit the reward to 500 points so I can only hope that and my eternal gratitude will suffice.
