[ubuntu-uk] Cannot print from Ubuntu

[David King]

I am having a problem with printing to my laser printer recently. 
Although it is connected, the print jobs are not being sent. The 
computer cannot seem to find the printer.

The printer is a Brother HL-5150D, I am using Ubuntu 8.04.1. It is 
connected via USB. The last time this happened, a few days ago, I 
rebooted the PC and when I was logged in the page was printed without me 
having to reprint it at all. It is like the computer cannot see the 
printer, but is sending the print job, which gets stuck somewhere, and 
will not go through unless the PC is rebooted. I used to have this 
problem a few years ago, when using Windows on a different PC. I would 
try to print, nothing happened, until I rebooted and then it printed.

This problem has not occurred before with Ubuntu or any other Linux 
distro and this printer, this is now the second time it has happened. I 
tried unplugging the printer USB cable and reinserting, I tried 
switching the printer off and on, I tried using the CUPS printer admin 
page in Firefox (http://localhost:631/printers) to look at what is 
happening, in that page I had to click on Start Printer but still 
nothing comes out of the printer.
