Lose Printer After Reboot

John,

Please set the printer so that it's not working again (reboot, etc), then go to http://localhost:631/printers

Is the printer 'Paused' and the button "Start Printer" is green?

Aaron --

Thanks for your reply.

After a reboot (cold, from power off) with the printer light "on", CUPS
says for "deskjet_3420 (Default Printer):
 Printer State: idle, accepting jobs, published

And toolbox says: Error: Device not found. Please check connection and
power-on device.

Originally this morning, on booted with the printer power off - had the
same messages as I now have after rebooting with the power light on.

I'll stay tuned!! Thanks again.

John

Are you using a usb hub or anything?

With hp-toolbox giving you the error "Device not found" can you run hp-check again and post the output?

Thanks!

Here's the output from hp-check after rebooting and confirming that
toolbox shows the Device Not Found error.

John

John,

For some reason it didn't come through.. (the hp-check that is) :/

Also when you are getting the error run:

/usr/lib/cups/backend/hp

and post that output as well.

Probably my bad.

Actually just run "/usr/lib/cups/backend/hp" in terminal. It's a tool that will tell us if hplip can see the printer.

I booted again this morning and then tried to run toolbox.py from the CLI. Of course the the GUI presented itself with the device not found error message. The command line response was similar:

It may be nothing, but how can the program find the device but not communicate with it? Is this turning out to be a permissions or path problem?

I haven't been able to reproduce this on Ubuntu 6.06 LTS and HPLIP 2.8.2

If possible retest with the latest release of hplip.

Thanks!

Thanks again Aaron.

I loaded 2.8.2 and rebooted -twice, in fact. On each reboot I got the
same error. Unless you see something glaringly obvious, I'll just live
with it until I install a newer Kubuntu.

Here's my hp-check output showing the communications error:

I don't see any errors, the device status is seems okay.

Are you using any usb hubs? Maybe try plugging the printer into a different usb port?

My laptop has only one USB port and I am not using an external USB hub.

It seems like hplip can't get the information about the printer that it needs from the usb bus. So this will check to make sure that the bus is returning the correct information.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Sorry for the delay, the lsusb output looks okay.

Is it possible to try upgrading to the latest release of hplip?

Thanks.

Aaron --

Thanks for your interest! The conditions have changed, but the results
have not changed. When I originally submitted this question, I was
running Kubuntu 6.06 and throughout the process I moved from the
original HPLIP 0.97 (?) provided by Kubuntu, to 2.7.6, to 2.7.10, to
2.7.12, and then to 2.8.3. I am now running Kubuntu 7.10 with its
provided HPLIP 2.7.12 and I still have the same problem. Somewhere
along the line I found a reference to an executable called "beh"
(backend error handler), that was pointed out as a possible culprit or
contributor to the problem. I subsequently removed "beh", but, of
course, there was no change.

In my mind, since very few folks (perhaps none) have HPLIP difficulties
of the kind that I have there may be a hardware issue with my older
platform (IBM Thinkpad T20) in that the on-board USB hub may not be
working the way the software thinks it should be working. If that is
the case, then since IBM saw fit to only implement a single USB
connection for this configuration, I'm probably just out of luck.

I know the HP DJ 3450 (detected as a 3420) is a low end printer and may
not be providing "typical" responses. Don't get me wrong, it's a fine
little printer and when it's connected and recognized, it prints well
and with reasonable quality.

If there's any more info that I can provide, please let me know. Thanks!

John

John,

Sorry I don't have any other ideas at this time. and I haven't been able to reproduce. It does indeed seem to be some sort of hardware problem.

Wish I could help more..

Setting to answered for now.

Thanks Aaron.
