HP Deskjet F4210

I mounted new printer and corresponding hplip… driver. The printer worked nicely.
Then scanning with Kooka was mounted, this also worked well, but the printer is not working anymore. I deleted the printer driver and mounted it again, but no success.

How shall this be solved?

You could try installing the more recent hplip version from Packman:
