Yeah we went down that path also.  Everything was current a few months ago when we had the problem.  Several people with several different printers are all having this issue.  What is weird is 2019 and all prior year softwares print fine on the same printer.  And 2020 state forms also seem to print fine.  It is just Federal forms.  I know ProSeries was working on a fix.  Have they released anything since Jan/Feb of this year?  Maybe I am missing that?  Although I updated the program last week for an efile issue.  Its weird for sure.
