[Bug 1955766] [NEW] Simple Scan gives no error when output filesystem fills up

[Steve Pemberton]

Public bug reported:

If the user tries to save the output of a scan to a filesystem that
doesn't have enough space, Simple Scan gives no error message. It
silently creates a truncated or empty file.

I don't know if this is relevant, but when I found this bug, I was
trying to save the scan to a mounted removable drive (a USB stick), and
I was creating a multi-page PDF.

[Bug 1920619] [NEW] Epson Stylus SX535WD does not print in Ubuntu 20.04

[Steve Pemberton]

Public bug reported:

I have an Epson Stylus SX535WD, connected to the computer via USB. It
prints correctly in Ubuntu 18.04. I recently upgraded to Ubuntu 20.04.2
LTS, and it no longer prints. The setup wizard seems to work. It detects
the printer correctly, and asks for permission to install drivers from
Epson. When I try to print, a message appears on the screen saying that
the job has been submitted. A few seconds later, another message
appears, saying the job has completed, but no output appears. The job
shows up as completed in the printer queue. I tried printing a test page
(Settings -> Printers -> Additional Printer Settings -> right-click the
printer -> Properties -> Print Test Page), and also printing a document
from LibreOffice.

I upgraded my hardware (motherboard and CPU) at the same time as Ubuntu,
and thought that might be the cause of the problem, but I booted the
computer from a live USB of Ubuntu 18.04, and the printer worked then.

I followed the recommendations at
https://wiki.ubuntu.com/DebuggingPrintingProblems, none of which fixed
the problem. Everything that the page tells me to check looks OK.

The printer has a built-in scanner, which works in 20.04.

Output from apt-cache (I'm not sure which of these are right or
relevant):
