Error's adding a network printer after hplib installation

Asked by K Homer on 2023-09-18

On a fresh install of Ubuntu 22.04.03 I have installed hplib-3.23.5

The installation appears to work correctly, however when I get to the stage of running the GUI to install my Networked printer I get a warning message telling me there is a KeyError: 'family class'

The printer I have connected to my network is an HP LaserJet 200 color M251n

After investigating the issue on the internet I came across a message recommending that the 'family-class' variable in the models.dat should be set to Undefined.

When I checked the models.dat file the closest printer i could find to mine was one called 'hp_laserjet_200_color_m251nw'

This already has the family-class variable set to Undefined.

Running the 'hp-setup' command the following happens

The first screen lets me select the type of printer, as my printer is connected to the network. I select the second option. Then press next.

The software searches for the printer and find my printer at the right IP address.

I select my printer from the list and press next.

At this point i get the family-class warning and the next button changes to 'Add Printer'.

I press 'Add Printer' the software thinks for a short time and then stops, in the background I get another family-class warning and the screen does not change.

At this point I cannot progress the installation of the printer. I have added the export of the terminal window below showing the messages i get.

Please could you help me resolve this problem.

Kind regards

Keith

Terminal export
