As there is no transparency, no shaded fills and no CIDFonts in this file, there is nothing which is really affected by changing the resolution for ps2write. Given the error observed above, I would guess this is another filter problem. If Felix can attach the PS from Till's test PDF, I can take a

Felix, The main thing is, I need the PS that actually gets sent to the printer so that I can get the device specific settings that are inserted by CUPS (and are not present in the "bare" Ghostscript output). Then I can create variants of the PS from Ghostscript, and "hand patch" the Postscript to

Till, Sorry, that's not quite what I meant by "inject Postscript". What I was hoping for was a way to bypass the PDF print queue (PDF is *so* unsuitable for that!), so that an end user can take Postscript directly out of Ghostscript and push it into the CUPS "back end" to have the PPD derived stuf

I can't answer that. I can say that Ghostscript's ps2write output is valid Level 2 Postscript - in other words, it is compliant with the language defined in the Adobe Postscript Language Reference Manual Edition 2. And not especially challenging Postscript, either. Let me ask this: if gcc fails t

Your file contains neither fonts nor CIDFonts, it is simply one big image. Whilst it is common practice for scanner produced PDF to use OCR to overlay the scanned image with non-marking characters (obviously, being non-marking, the actual font used does not really matter), this file does not do so.
