HP Toolbox fails to recognize new printer


I have just installed a new HP Deskjet 5740 on Kubuntu 5.10 (KDE 3.5) and it works great. However, when I try to run the HP Toolbox provided by the hplip package I get the following error:

Code:
No installed HP devices found. 
After setting up a printer, you must press F6 or choose 
Device --> Refresh All for the printer to appear in the 
HP Device Manager

Note: Only devices installed with the hp: CUPS backend 
will appear in the HP Device Manager.
The CUPS web interface shows my printer installed, though configuration from the web interface is disabled. Pressing F6 does nothing, and I can see the Device menu in the program, but whenever you click on in the error dialogue the program closes. You, of course, can't click the menu without closing the dialogue.

I have tried rebooting the system as well as turning the pritner off and back on. Does anyone else have an idea as to how I might make it recognize my printer?

When you configure CUPS, you must enter the hp: URI instead of "socket://" or other types of URIs. To get the URI, you run
Code:
hp-makeuri <ip address>
and it should look something of this format:
Quote:
hp:/net/Deskjet_5700?ip=192.168.1.10

Do you mean the IP of my computer on the local network? If so, then 'hp-makeuri 192.168.1.140' returns the following error:

[ERROR]: Failed (error code=12). Please check address of device and try again.

Nevermind, I see. You were thinking it was a network printer. 'hp-makeuri /dev/usb/lp0' created the following output:

CUPS URI: hp:/usb/Deskjet_5700?device=/dev/usb/lp0
SANE URI: hpaio:/usb/Deskjet_5700?device=/dev/usb/lp0

The HP Toolbox still shows the same error and the URI listed under the KDE printer manager is still ipp://justin:631/printers/HPPrinter. I tried to find a place to change this under properties, but was unsuccessful.

What I did notice is that under 'Interface' it shows the USB location as 'usb://574X?serial=TH65U120C5049T'. It seems to me, however, that this is just due to the fact that the printer is configured and so now the system recognizes the device and asigns it a name based on that.

Edit: I tried removing and reinstalling the printer just for kicks. The URI shown under the KDE config is still the same as above.

You can enter the URI in the CUPS web interface (http://localhost:631/, enter root password).

so the printer page on the CUPS web interface says the URI is 'usb://574X?serial=TH65U120C5049T' and not the 'ipp://justin:631/printers/HPPrinter' that the KDE printer information page shows. Odd, but whatever.

I assume the URI under the CUPS web interface is what I need to change? There is a button that says Modify Printer, but the web nterface is disabled. It says at the top, "Administrative tasks have been disabled for security reasons. Please use Menu System > Administration > Printing."

I tried to enable the cups web interface using the guide here, but had no luck. The text about the interface being disabled still shows and the root password still doesn't work. I also set root as a cups admin via these instructions.

Under the 'Users and Groups' settings I noticed the user cupsys was disabled. I enabled it as well as adding to the shadow group as the previous instructions indicated. The disabled message is still there and I still can not login to the web interface via root.

Edit: I am restartings cupsys after each of these changes via 'sudo /etc/init.d/cupsys restart'.

Problem solved. I was making things way more harder than they needed to be, no surprise there. I simply opened '/etc/cups/printers.conf' and changed the printer URI there to the new one. Problem solved, everything works. I feel stupid.

Oh well, hopefuly this thread can help somebody in the future.

Also, the helping hand is much appreciated spooon.
