The driver is installed and a test page prints properly, but no document will print. When printing, it gives only a few lines of nonsense characters at the bottom of the page. Also, I just discovered that the scanner no longer works and, through GIMP, gives a "could not send command to scanner" message. To clarify, this printer was working well before upgrading to one of the recent Ubuntu versions but, as I don't use it often, I don't know exactly when it stopped but I believe with 18.04.
I've uninstalled and reinstalled the drivers several times and read and tried all tips I can find online but nothing seems to help. I also have a network Epson WP-7520 that has a few scanning and printing issues from Ubuntu and I presume it uses the same drivers but most of the time it works fine other than not reporting ink levels.
Any logs or command outputs to post that might help, please advise.
sudo sane-find-scanner gives:
sane-find-scanner will now attempt to detect your scanner. If the result is different from what you expected, first make sure your scanner is powered up and properly connected to your computer.
No SCSI scanners found. If you expected something different, make sure that you have loaded a kernel SCSI driver for your SCSI adapter.
found USB scanner (vendor=0x04b8 [EPSON], product=0x08c8 [EPSON XP-620 Series]) at libusb:002:003 Your USB scanner was (probably) detected. It may or may not be supported by SANE. Try scanimage -L and read the backend's manpage.
Not checking for parallel port scanners.
Most Scanners connected to the parallel port or other proprietary ports can't be detected by this program.
Running scanimage -L shows hundreds of lines but ends with:

device ‘epson2:net:192.168.0.25’ is a Epson PID 087C flatbed scanner

The XP-620 also has the most recent firmware.
The simple-scan utility seems to work but the Image Scan! For Linux (popup says: Scan documents and images with your Epson scanner) does not.
