output). If I edit the PS file in Notepad and change all references to OP_Times_New_Roman to Times-Roman (the closest [Adobe] system font), then I can edit the resulting PDF, but of course the Adobe font is noticeably different from the OP font. The PDFs generated from the DirectPS are on average bigger than those generated via Windows. Does this suggest that fonts are not being embedded? On the other hand, if font embedding fails, 

My guess would be that text in embedded fonts can't be edited.
That's understandable, but shouldn't the local font (TimeNewRoman) be substituted?
There is for example the point that in an embedded font one need only embed characters actually used in the document. 

... altho' there is an option in Distiller to turn off subsetting.
The fact that direct PS files are bigger might indicate that they embed fonts whilst the Windows driver does not.
Sorry, I got my words confused -- what I meant was the DirectPS PDFs are NOT significantly bigger than the alternative, which they ought to be (I would have thought) if font embedding had taken place (the DirectPS files are approx. 4x the size of the PS files produced when DirectPS is off).
As I hinted there usually is in Windows drivers a section where you can choose what to do with fonts, either map them to standard PS fonts which are assumed to be in the PS device or download them. This section can be difficult to locate.
Presumably the problem is that you're using the same driver and only changing the direct PS setting - so there can be no change in font mapping settings? 

That's true.
PDF editing is not a big issue - in fact, it strikes me as a last resort thing. But I thought it was interesting that DirectPS resulted in non-editable PDFs (not just from Acrobat, but also the PDF creator built into MacOS).
