Jon: thank you for your hint, didn't spot it until now.
Just returned to post the workaround I found: on Linux/Ubuntu on the "Render"-tab (or similar, in German it is called "Rendern") of the print dialog there is a radio button "Bitmap" vs. "Vector", the latter preselected. Selecting "Bitmap" and a resolution that fits the printer (say 300 dpi) gives a printout that matches the screen, and renders also Arial Black bold italic the way it should.
