Ubuntu Installation :: Printer USB Cable Port Not Found On 10.04

I have upgraded from 9.04 to 10.04. 9.04 found my usb connected printer ( LaserJet 6MP) with no problems. But 10.04 will not find the usb port to which my printer is connected. I have searched for a solution on the forum, and others seem to have a similar problem, but not recognized it. For some it seemed to have self corrected, but I am having no such luck. I have downloaded hplip from [URL]

Following their instructions, I have run "hp-setup" in Terminal. This gives the following output:
Code:
cs@cs-desktop:~$ hp-setup

error: No devices found on bus: usb
After disconnecting and reconnecting the printer cable, I used the command "dmseg| tail"

Terminal output:
Code:
s@cs-desktop:~$ dmesg | tail

I interpret this to mean that the printer is seen from this command. Yet when I do the "lsusb" command, I get this output:
Code:
s@cs-desktop:~$ lsusb
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 003: ID 050d:0002 Belkin Components
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
This to me indicates that the printer is not seen by the "lsusb" command.

I would like to get my printer printing. I am trying to get hold of an older parallel Centronics printer cable with a DB25 at the other end to see if I can get the printer working with it. Have others done this with success?
