I am not sure that would work in all cases anyway - if the user chooses an 
unusual font, one that does not map neatly to the standard Type 1 
postscript fonts, the postscript driver would be free to send the font as a 
bitmap or some vector graphics which would be completely unintelligible to 
ps2txt.

The only way i can see this working is if you have some OCR software 
available to read the rasterized postscript.  Again if an unusual font is 
chosen the ocr software may not be able to recognize it.

And if the user forgets to put the number in or puts "fax-number" by 
mistake how do you report the error?
