My local library "lends" ebooks, i.e. you download a PDF file but it will only open for two weeks and it only opens with the actual Acrobat Reader, not the non-proprietary PDF-viewers. I "borrowed" a Spanish grammar workbook, and it being a workbook I'd like to print the worksheets on my level to do them. And the ebook actually allows printing in the Acrobat Reader, but the result looks very low resolution and bad quality. Is this some perverted outgrowth of the DRM or can I do something, like fiddling with something in the Acrobat Reader, to make print output normal?
