LibreOffice and FreeOffice Textmaker cannot print correctly

A problem that started in openSUSE Leap 15.3 is worse in 15.4.

Neither LibreOffice (7.3.6.2) nor FreeOffice 2021 Textmaker (installed just to test if LibreOffice is the problem) can print properly to PDF or to my printer (HP LaserJet Pro 200 Color M251NW).

Starting LibreOffice in Safe Mode does nothing (again suggesting LibreOffice is not the problem).

The problem seems to vary somewhat by document.

Desktop computer system:

[LEFT] AMD Ryzen Threadripper 1950X (16-core/32-thread)
4.0 GHz Precision Boost (up to 4.2 GHz with XFR)
40MB cache memory
64 PCIe Gen3 Lanes

I would like to attach an example document. I guess I post first?

OK first things first. How do I attach a document or image of the sample document.

The image attachment displays as an image in the editor but Preview Post ends up displaying lines of text not the image.

Thank you.

For long pieces of computer code and for images, there is a SUSE/openSUSE paste site.

For long code sessions it is easiest to use the susepaste tool:

some command | susepaste
Pasted as:
   https://susepaste.org/74995563
   https://paste.opensuse.org/74995563
Link is also in your clipboard.  

You can also go to
https://susepaste.org/ and upload there (for am image see the word Image at top-right).
After you did this, you can copy/paste the URL from the page as shown in the address bar of your browser (and not the URL of the image itself). Paste this using the Link button (the one with the globe) from the toolbar of the post editor.

Thank you for the susepaste prompt! I have made a note to not forget.

I think I have a solution.

It seems at some point my favorite LibreOffice font (“Cantarell”) got kicked off somebody’s good list of printing fonts.

I can change the font to any number of other fonts and a document will print just fine from LibreOffice to PDF or the HP printer.

What Cantarell did to offend anybody is a mystery.

You can change the Cantarell font in entirety within LibreOffice without doing it manually:

Hamburger menu -> Tools -> Options -> LibreOffice -> Fonts gets you to the wholesale font change pane.

It is a long standing OpenOffice bug:
