We recently changed our fax number and now the end is cut off when printing it on any/all forms (Quote, Ack, PL, Inv, PO).
At first I assumed the box was not big enough, so I widened it by a 1/4" or so. No difference.
Looks fine on screen, AND if you create a PDF (either directly or by emailing) looks fine on screen AND prints fine.
It's just the last 1/3 or so of the last digit.
There is no other box on the page that's covering it up.
