Could you correct me if I am wrong in this line of reasoning: Acroread
coverts pdf files to ps files but does so in an incorrect manner and
therefore (because acroread source is unavailable) gs is altered to make
up for the bug in acroread and then all goes as planned. I think I am
correct about this but it leaves the question: Can't you use gv to print
pdf files and therefore (1) avoid altering gs for acroread's shortcomings,
and (2) use all free software? Cheers, Colin.
