Nothing there.
Anyway, in my experience, a bad font can be the source of the problem.
Old TTFs are notorious.

reset your printer settings and try again (maybe some kinda "Dithering Mode") causing problems

I have made some progress. After having all redone (created a new .sla file by copying all texts and graphics on the given template), I have now a .sla file that prints correctly all fonts, but exported PDF still prints bad. sla file is attached.

I have reinstalled Scribus 1.6.7 that responded wrongly to keyboard arrows. I have run SFC /scannow, DISM, and updated Windows 11. Now I am able now to create a PDF that prints correctly by using NovaPDF as printer (exporting to PDF from Scribus still does not work). All my fonts print correctly with NovaPDF.

Limeware.com keeps files only for 48 hours, unless I open an account, which I did not do.
