How to remove Hplip - what is the command to run on the terminal ?

Hplip 3.11.5 has already been downloaded and installed and there is a directory named hplip-3.11.5 in my home folder. Perhaps all this should be completely removed.

I propose to re-install it again as suggested by actionparsnip.

Have installed Hplip from the Ubuntu Software Centre and both printers are working again.

The same problem again this Monday morning - both HP printers not working. Could not even install the plug-in - no resonse.

Have downloaded Hplip-3.11.5.run and installed it over the existing Hplip-3.11.5 installation and now the HP printers are working again.

The same problem again this Tuesday morning - both HP printers not working. Printers not working with Libre Office Writer or with Libre Office Calc or with Evolution Mail.

It seems to be some configuration problem.

The plug-in had to be re-installed again and now the HP printers are working again.

There already is a Hplip-3.11.5 directory in the home folder with many sub-directories since hplip-3.11.5.run is already installed.
Any suggestions to get over this daily problem?

Thank you
