Trouble setting up hplip and cups - printer ppd fails

[ng0 <ng0@libertad.pw>]

I'm having a hard time getting hplip and cups to recognize the
PPD for my printer (one of those which are not network enabled,
which is why I feel safe enough sharing the model and serial
numbers here).
Starting at https://gnunet.org/bot/log/guix/2016-12-24#T1240133
you can find the discussion adfeno and myself had about the
problem.

In addition to the output below, my user is member of lp and
lpadmin and cups webinterface complains about hpcups if I add the
printer through cups (which you should not do with HP, at least I
was told so in the past and learned that this printer does not
work with cups pdds but with hplip ppds it works):
Idle - "File "/gnu/store/pd200v2q8vdxy6ycsxjsskxavc5q2jvk-cups-server-bin/lib/cups/filter/hpcups" not available: No such file or directory"

I never was a fan of the terminal setup they have, so I'll try to
add the Qt interface next week. But this doesn't seem like the
problem here.
