Welcome to the forum!

This sounds like a font issue.

The first thing to try is to make sure that the music fonts are correctly installed.

As a test (not as a solution), check whether the music fonts display correctly in other programs (like e. g. in a word processor).

I am not sure trying a word processor program would tell anything unless you used the same font as you did in Finale. You can reinstall just the fonts and that probably a good idea to try. Perhaps a complete reinstall of Finale is a better idea.

I see you still have v26 now may be a good time to upgrade to 27.4.1. It is well worth it, IMHO, of course.

It turns out it's a Kyocera printer issue.
