error when printing: because the default printer could not be opened.

I have been using this program since 2020 and all of a sudden when I try to print (4x6) I get an error: because the default printer could not be opened.  I can print out of windows with no problem.  It only happens in my photoshop elements program.  I took it to a computer repair and he could not figure it out.  Please help!  Has anyone had this happen?  I print specialized sizes and need this program to work.
