When I upgrade from Ubuntu 18.04LTS to Ubuntu 20.04LTS will my Epson ET-2750 printer setup from 18.04 upgrade to 20.04?
I could not install the Epson printer on 20.04 standalone. The only difficulty I could see was 20.04 would not accept USB as a connection; 18.04 did accept a USB connection.
This is a possible issue with ippusbxd. Ubuntu 20.04LTS introduces ippusbxd as a default installed package to promote auto-detection and auto-installation (using cups-browsed) of a USB-connected device.
Unfortunately, its usefulness and reliability has become very questionable. So much so that it has been replaced by the much better ipp-usb on Ubuntu 21.04. Whether or not it is the problem in your case, you are advised:
ippusbxd from the system.Should auto-detection and auto-installatio still be an attractive proposition, the advice here applies.
You are correct, ipp-usb is no better for my Epson ET-2750 than ippusbxd was. I upgraded from Ubuntu 20 LTS to 22 LTS and my Epson would no longer print. I found ipp-usb, removed it and installed lsb. I called up the printer settings, clicked on "additional printer settings", found my printer and installed it. I ran a test page and it was fine.
I don't know much about printer daemons, but it looks like ipp-usb, also known as ipp-over-usb, does just that, it ignores the Epson USB printer.
My concern would be an Epson usb printer and an ipp printer on the same machine; would lsb take precedence over ipp? I don't know.
Good luck.
