The ink for my printer is only slightly less expensive than unicorn's blood, plus I can buy the book used for $10. The problem is being able to extract sections in order to make them available/accessible to students. That's why I need pdf.
When I used AdobeAcrobatPro, the conversion worked but it gave the information of the directory path and my computer at the bottom of every page, which was not ok. Then, I tried the Print under File Menu via Firefox and it saved it but the file was corrupted. In Safari, using the same technique, it also included the directory path on the bottom of every page.
I'll try calibre and see what happens... Worked like a charm. Thanks!
