If you having problems printing a PDF in the library you can check to make sure that you have selected the whole document to print. You can verify this by selecting print range>all in the print menu under the file tab.
To eliminate slowed or stalled printing when you have a large or high resolution PDF, you can save the document to the desktop and print from that version rather than printing directly from the database.
Verify that your computer is connected to the printer correctly.
