Can I assume this is a PDF?  Most likely it's a bug in either poppler or
cairo.  Probably cairo as it only effects printed output.  You can check
the print preview in evince.  If the print preview is bad, then it's
most likely cairo.  If the print preview is good, then it's some weird
interaction with just your printer that is going to be really hard for
anyone else to reproduce.

To confirm the above, you can run "pdftocairo -pdf in.pdf out.pdf" and
then look at out.pdf.  If out.pdf is mostly black, then it's either
poppler or cairo.  If you're comfortable with compiling, you can try
compiling poppler and cairo from their git repos and see if the problem
has already been fixed.

After that, if I were debugging it, I would clean up the PDF with
"mutool clean -gidf in.pdf out.pdf" and use a text editor to cut parts
out of the PDF until I had a managable test case, removing any personal
information at the same time.  If you're comfortable emailing the
document directly to me I can do that, but without the document there's
not much anyone can do.

And note, I'm not saying that it will be fixed, just that I could
forward a test case to the poppler or cairo bugzilla.

No, sorry.
