Cannot add HP P55250dw printer from hp-setup

Hi,

Were you able to add the printer by selecting the USB option?
If you have your printer connected in Network, can you please try "hp-setup <ip of printer>" command to add the printer and update me the results.

Also share the hp-check output.

Thanks,
Srinivas Teja.

thanks for your answer,
The printer is connected to our network, and I can't connect it via USB at the moment, since it's used by others.

Here's the output from "hp-setup <ip of printer>".

Once I run it I see the printer already selected in the "Select From Discovered Device" window, so I click "Next" and get the first traceback error you see below. Then the "Next" button changes in "Add printer" and once I click it I get the second error. I then click "Cancel" ad get the "Done" message on the terminal.

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]
