Error installing drivers for HP printers

I am following the wiki installing the drivers for an HP LaserJet, however I get the following error:

nix run nixpkgs.hplipWithPlugin -c sudo hp-setup

HP Linux Imaging and Printing System (ver. 3.19.12)

Is this a python problem?

You may want to try starting it in interactive mode (hp-setup -i).
When it asks…

Would you like to install another print queue for this device (y=yes, n=no*, q=quit) ?

…answer no and after that your printer should start working.
