I have replaced the ink carts. and have unplugged the power for sixty secs. trying to reset it but it will not. I am running 32 bit ubuntu 12.04, using the hplip driver. It has the Blue ink light flashing and I have replaced the cart. with a new one. it printed for 15 sheets of paqper and it paused. I've only had the printer for 6 weeks but have plugged into an eight port router.

What did you find when you looked at in CUPS (http://localhost:631)? You might be able to restart it from there.

You could also use HPLIP to check its status (hp-toolbox launches the GUI if you have it installed and it's not on the menu; ls /usr/bin/hp* will show you what hp utilities you have installed).

Have you played with the Cups browser interface?

http://localhost:631/printers/

If you haven't yet, pause and resume your printer there from the Maintenance menu. It will prompt you for a username (root) and password.

There's also the cupsenable command. If your queue is hplaser, try:
sudo cupsenable hplaser


I find that Cups is alternately wonderful and terrible. I can go for a year with not a single problem and then run into a spell where I can't get anything to print.

At localhost:631/printers I found:

HP-Officejet-6000-E609a (Paused, Accepting Jobs, Not Shared, Server Default)
Description: HP Officejet 6000 E609a
Location: Network
Driver: HP Officejet 6000 e609a, hpcups 3.12.2 (color, 2-sided printing)
Connection: hp:/net/Officejet_6000_E609a?zc=HP6EDCB8
Defaults: job-sheets=none, none media=na_letter_8.5x11in sides=one-sided

I can find nothing to unpause it.

I tried this but:

willis@willis-laptop:~$ sudo cupsenable hplaser
[sudo] password for willis:
cupsenable: Operation failed: client-error-not-found

In Printer Properties the State is reported as:

Stopped - /usr/lib/cups/backend/hp failed

I resumed the printer in the maint. drop menu and then did test print but it is pausede again.

I don't have an answer because I've never run into this particular problem, but I have a couple of thoughts.

1. Did it work before and does it work with other computers attached to the same network? If it works with other computers on the same network, that narrows the problem to something in that particular computer.

2. Try deleting the printer in CUPS, then reinstalling it using HPLIP.

3. If the printer is DHCP, try giving it a fixed IP address and test again.

4. Connect it directly to the computer and test again. It's not that I think the network is necessarily part of the issue, but this removes many variables.

Good luck and keep us posted.

That narrowed it down to my network. I plugged it with the usb and it prints so it's not the printer at all. I've got to rethink everything and thank you.

You are most welcome. Every possible cause eliminated is one step closer to the solution.

Keep us posted.
