Yeah, this is one of the printers HPLIP does not support out of the box,
because it uses a patent-encumbered compression method (JBIG) as part of
its transfer protocol. And as you say:

this is also the reason why foo2zjs is not in Fedora.

FWIW, I think we could get better support for that printer if somebody wrote
a Free drop-in replacement for HP's binary plugin using jbigkit, which
would allow using the printer with HPLIP (without non-Free binary-only
software) rather than the hacked-together foo2zjs driver. But for now
foo2zjs is the best you can get in Free Software for that printer.
