Status in HPLIP:

On Ubuntu 20.04 focal (with -proposed enabled). HPLIP=3.20.3.
Previously there was a libmtp (udev) bug erroneously detecting HP
printers as mtp devices. This was fixed. Now, I can try to scan-- from
both simple-scan and hp-scan, hplip errors out:

Printer/scanner is an Officejet 4635. Scanning previously worked just
fine a few months ago. Regression?
