Print PDF's directly to iTunes
To print a PDF to iTunes for syncing with your iPad or iPhone first you need to make a shortcut. Goto Applications and find iTunes, right click or control click on the iTune icon and choose Make Alias.
Next drag your newly created alias to the ~/username/Library/PDF Services or /Library/PDF Services to make it appear for all users.
Once that is done rename the shortcut to Save to iTunes or whatever you want to name it that is meaningful to you.
Now Open any program and choose the Print dialog. Click on PDF and choose whatever you named your alias you placed in the PDF Services folder. Give the PDF document a name.
Finally open iTunes and click on books and you should find your document in the list. Sync your iPad and iPhone and the documents should appear on your devices.
