Adobe Acrobat and Adobe Reader cannot read or activate Schema eBooks. You must use Digital Editions (or a compatible eBook reader) to solve this issue.


12. I am having trouble printing my eBook on my Mac using ADE with my HP (or other brand of) printer.


There have been dramatic changes in the most recent versions of OS X that have led to countless Mac users complaining about many kinds of printing problems after recent OS X updates. These problems result from a complete overhaul in the printer driver approach that Apple has taken. Many manufacturers (and especially HP) have not been able to update all of their printer drivers quickly enough. To add to the confuson, the symptoms of these printer driver problems involve inconsistent print problems (some files print perfectly, some won't print at all, some print blank pages, some print half pages, etc.)


Apple and Adobe both strongly recommend that users with PDF-based printing problems download the most recent software updates for their printer drivers. These are usually available from the printer manufacturer or from Apple. They also recommend uninstalling your current printer drivers and reinstalling the new ones from scratch. You may find other helpful suggestions by following the links below:
