Kernel requirements for HPLIP (not working) [SOLVED]

My printer (connected to the network through my router with a static ip address) used to work fine with HPLIP and CUPS. When I last tested, I was (and am) using a custom-compiled zen kernel; the relevant modules that I compiled (separately, not into the kernel) are plip, ppdev, and parport. I am guessing that it is a combination of package upgrades and my custom kernel that is causing the problem below:

My printer is detected by CUPS, and I can see it on localhost:631. When I send jobs to it, it begins "processing" them, then hangs on a (to-print) page and I see the message 

/usr/lib/cups/backend/hp failed

I deleted the printer from CUPS and re-added using 

sudo hp-setup

The process goes just fine, with hp-setup only throwing a warning about how dbus must be running for the PC to fax (with which I am not concerned).

When I run hp-testpage, I get this:

redscare:~> hp-testpage 
warning: python-dbus not installed.

Re: Kernel requirements for HPLIP (not working) [SOLVED]

I had a challenge similar to your s after a few updates .  Do you have HPLIP installed ?

   HP Device Manager - Has a trouble shooting  section which worked in my case . Actions , Help

    and in my machine ;  file:///usr/share/doc/hplip-3.9.12/troubleshooting.html it asked to run
     
      

 hp-check -t

which I did and followed the prompts , it would run checks and tell       
         
        what was needed  to install , minor stuff but it  worked .  Hope it helps I realize I wasn't

   none to specific but ,

Re: Kernel requirements for HPLIP (not working) [SOLVED]

I didn't have python-dbus installed, which I did. hp-check -t still throws some errors, but I don't see how they are related to the printer not working (more scanning-related issues). Here's the new output of hp-check -t:

I hate to bump but this is kind of urgent, if anyone could give a pointer it would be greatly appreciated.

Re: Kernel requirements for HPLIP (not working) [SOLVED]

I cannot help much, But at least make sure you have the packages flagged as missed dependencies installed. Especially check for these:

pacman -Q pil pyqt

and optionally(?): 

pacman -Q python-libnotify sane

Also see the "Optional Deps" section in 

pacman -Qi hplip

To know or not to know ...
... the questions remain forever.

Re: Kernel requirements for HPLIP (not working) [SOLVED]

I removed all the crap that I installed; I realized that cups was having problems connecting to the printer because the uri used the hostname; for soem reason this was bad, and when i changed the zc=HOSTNAME line to ip=IP.IP.IP.IP in /etc/cups/printers.conf and /etc/cups/printers.conf.0, everything worked.

If anyone runs into this problem keep in mind it is not a kernel issue. Perhaps a mod can retitle and move the thread so that people are aware of the problem?

Re: Kernel requirements for HPLIP (not working) [SOLVED]

This worked for me. Make sure you use ip= and not zc=
