Hi Liam,

the printer part is solved, see my other message. As for this:

of course you are right, sorry. All I can say is that this situation
got me completely by surprise. Installing a Linux distribution and
finding it unable to recognize and handle by itself a common printer
and monitor... felt like being back in the 90s, to manual modeline
calculations and manual compilation of drivers.  Especially because
both printer and monitor had been detected and working flawlessly for
years on several other distributions.

Here is the relevant information: the monitor is connected via DVI
cable, the "Graphics" entry in the Settings/About tab of Gnome says
AMD Rs780, the motherboard is an MSI MS-7641 (from dmidecode), and
there are no "additional drivers" listed in the Software and Updates
Gnome tool. This is the output of the relevant part of lspci:
