Bug Description

Hi, I'm using a HP Laser Jet Pro MFP m28a Printer and Scanner.
The printer works well but the scanner needs plugin.
When i type the command "hp-plugin -i" it report the bug: "Network connection not detected"
My O.S. is Ubuntu Mate 22.10

This is the "hp-check -t" output:

[code]hp-check -t

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]
