Are you talking about the Qt-based hplip-gui stuff? I'm guessing you
are.

You should have access to the full capabilities of the entire set of
print engine / printer filters _via CUPS_ -- after you've installed
the printer-driver-hpcups and printer-driver-hpijs .debs . HP's
separate hplip-gui aka 'HP Device Manager' (aka 'Toolbox') becomes at
that point superfluous.

The 'hpcups' package furnishes the basic CUPS raster driver (the logical
way to print to many but not all HP inkjet and laster printers). The
'hpijs' package provides the HP InkJet Software (IJS API) support, the
way to reach most HP inket printers and a few laser printers.
