No longer able to scan to file

When I had ubuntu 18.04 I had a Scan icon in my favourites which opened a control screen. I forget what it was called, but this screen showed me what I had scanned and had a few basic settings for text or image quality , orientation, page number rearrangement, and the option to save it to a file. After I upgraded to ubuntu 20.04, the scan screen could not connect to the printer, even though it is connected with USB cable, and when I uninstalled and reinstalled HPLIP the icon disappeared completely. The scanner still works but I have no way to save a scanned document or image. The printer function still works OK. The printer is a fairly new HP Envy 5032. The printer check is as follows, but I am not a computer geek and I don't understand any of it:

hp-check -t

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]
