with my app I print documents with PSCRIPT and on my PC the PDF-File looks correct:

but some of my clients open the PDF-File and get this:

Used fonts: APS_ARIAL, APS_COURIER
I looked into the PSCRIPT.DLL and find out, that the engine to produce the PDF-File is made by Synactis (PDF In-The-Box version 4.04). Is there any update?
