Hi,

I tried to print from a D-Bus free system to a HP DeskJet, WiFi connected, 
printer.
CUPS is installed but complained about missing back-end.

/var/log/cups/error.log:
Stopping job because the scheduler could not execute the backend.
File \"/usr/lib/cups/backend/hp\" not available: No such file or directory

hplip, which I know works with the printer, depends on D-Bus and is currently 
not installed.
What "backend" am I missing?
Can I print without D-Bus?

Regards,
Menelaos

I use hplip and yes dbus is installed.

I run a very minimal ascii/ceres system and following the trail of things dependent on dbus - well, unless somebody knows better it looks like we are stuck with it.

Apart from being unable to print, what happens in your system without elogind or the various 'pam' things that need dbus?

What are you using instead of them?

I just might be about to learn something new!
