To be precise: Black lines were black,
but pale gray areas were an even paler yellow.
I've just discoverd that the printer does
the right thing with text from a pdf.
The black ink cartridge is getting used,
just not enough.

I used HPLIP, but it has been a while, so no details.
Before remembering HPLIP, I'd tried to install the printer with just CUPS.
It would not print.
Using HPLIP, I got a rather long-named queue that would print.
The other queue, the one with the name I wanted,
will accept jobs, but never finish them.
