In DiscussSV Ray Rippey reported Preview would not work without a Printer Driver installed:
I had a problem the other day with the program just didn’t go anywhere
when trying to preview. Turned out the printer driver disappeared when
the guy unplugged his printer. Installed the Microsoft xps document
driver and the preview worked. Just throwing this out there.
