I solved the problem - kind of.  It was caused by the printer drivers needing to be reinstalled.  Now that they are, I can see a portion of the bill on the screen -- but not the whole thing.  only about 1/8th of each page.  If you have any idea how to fix that, please let me know.

First tey reinstalling your video driver. If that doesn't work check your advanced display setting. Are you at normal or large?

Reinstalling the driver doesn't help but changing the display size settings does (kinda).  If you mean the advanced display settings in Windows 8.1, I am set to "Default" rather than "Small" on retina resolution.  If I access the display settings from Control Panel, the slider that slides between Smaller and Larger is 3/4 towards Larger (i.e. larger, but not largest).  I slid it to 3/4 towards Smaller -- it fixes the problem!!  But it makes all the text in all my applications including Timeslips too small to be functional.  Still, this allows me to at least preview the invoices, then slide it back.  Any thoughts on how to avoid this hassle?  Much appreciated and koodoes to you!
