Can't scan in Ubuntu 18.10

Since upgrading to Ubuntu 18.10 from 18.04 last week I am unable to scan. I have used the Ubuntu version, then removed it and downloaded the version from hplip web-site.

I can currently print but not scan. Simple scan says "failed to connect". Xsane has "Failed to open device hpaio:/usb/ HP_LaserJet_Professional_M1212nf....." Error during device I/O

Output of hp-check -t below

This software comes with ABSOLUTELY NO WARRANTY.
This is free software, and you are welcome to distribute it
under certain conditions. See COPYING file for more details.

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the
HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies
are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro
supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball
has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode
will check both of the above cases (both compile- and run-time dependencies).

Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]
