Because of xpdf's lack of support for some new pdf features which I commonly deal with, I am trying to replace the pdftops cups filter with a filter that uses acroread. So far I have managed to make everything work perfectly except that acroread seems to insist on shrinking the pdf to fit on a page with margins. The shrink is very noticeable and completely unnecessary because all of the pdfs I print already have margins.
Through experimenting, I have discovered that through acroread's print window, I can turn off shrinking, but it defaults to being on. The same default seems to apply via command line, but the only option acroread has relating to shrinking is to turn it on. Am I missing something?
