Cannot share printer over network (FIXED)

[spode]

I have a brother HL-2030 printer connected via USB, and it works fine from the local PC. I have tried to share the printer over the wireless network to another PC, also running Kubuntu 9.10. I have tried to configure this via both Printer Configuration in System Settings and using the CUPS web interface without success. This worked faultlessly on Jaunty - the shared printer showed up on the other system and I could print to it without problem.

Is anyone else having trouble with this?

Re: Cannot share printer over network

I have a Brother MFC-210c multifunction printer connected via usb on the main computer, and I am having problems trying to access it using Kubuntu on my laptop.
I've set the printer up on my home network of 4 computers to be the shared printer for all, but I can't seem to get my laptop to find it using Kubuntu.

I had no problem sharing my printers using the CUPS interface. Be sure you have checked the proper boxes under "Administration" to enable printer sharing.

How do I access the CUPS interface in Kubuntu? I've heard of it before a few years ago when I was using Ubuntu 6 but I'm just getting back into things now with the all-new Kubuntu o/s.

Open your browser (Konqueror or Fireox) and enter http://localhost:631 in the location bar.

I noticed new packages for CUPS came down in some updates today, but still no joy with sharing the printer over the network. I even tried purging and then reinstalling the CUPS packages and adding the printer again to see if this cleaned up the config files, but no joy.

Strange. This is using a fresh install of kubuntu 9.10 on both machines. Nothing else has changed, and it worked fine on 9.04.

Re: Cannot share printer over network

Have you installed the printers using the CUPS interface and changed the settings under the "Administration" tab in the interface?

Re: Cannot share printer over network

Yes, have tried through the CUPS interface, and made the changes to share the printer in the admin tab. Also changed the CUPS settings on the kubuntu client to show printers shared by other systems.

I am out of ideas.

Re: Cannot share printer over network

If I allow remote administration via the CUPS web interface, I can connect to the web interface of the CUPS server from my client system. It is just printer sharing that doesn't work.

EDIT: I got this working. Not sure which change or combination of changes did it, but I:

1. Purged and reinstalled cups

sudo apt-get purge cups
sudo apt-get install cups

2. Installed the snmp packages - CUPS uses SNMP to broadcast network services. snmp was not installed on my system, so I added it:

sudo apt-get install snmp

3. Blacklisted the usb printer module, usblp, as detailed in this bug:
https://bugs.launchpad.net/ubuntu/+s...ps/+bug/417977
This is done by editing /etc/modprobe.d/blacklist.conf and adding the line

blacklist usblp

I then rebooted the system and deleted and added the printer again. Still nothing on the client PC until a few hours later, when the shared printer showed up in both the CUPS web interface and KDE System Settings.
