Ubuntu 20.04 misses printer, and correct monitor resolution

There seems to be a Linux driver here:

Found via:

https://linuxforums.org.uk/index.php?topic=10728.0

But it looks very old.

There's also a howto here:

https://tutorialforlinux.com/2018/03/24/driver-epson-xp-302xp-303xp-305xp-306-ubuntu-18-04-how-to-download-install/

It's a horrid page. Note that the word "Here" is generally the hotlink AFAICS.

Slightly more info here:

I am surprised that you do not say what graphics adaptor you have, how
the screen is connected (from what port to what port, on what kind of
computer, via what kind of cable). Without that info we can't offer
much.

What kind of graphics adaptor/chip? Do you have a driver installed? If
so, what driver & version?

If not, have you looked at what the "Additional Drivers"  tab in the
"Software & Updates" tool says? I can't give more exact info on how to
open this as you have not specified what desktop you're using.

If it's GNOME, open Settings, then go to Software & Updates, then look
for the "Additional Drivers" tab. It should be about the 5th tab.

> but isn't there a... more modern solution?

Well, yes. Make sure you've got the right graphics driver installed
and for any modern-ish flat-panel display, connected over a digital
interface (i.e. *not* VGA -- so, meaning HDMI or DisplayPort or DVI)
it will auto-detect the native resolution and use it.
