CentOS - Sep 2008 - HAL adds printer twice

Hi,

When I want to configure a printer, say an HP Deskjet 940, I install 
hplip, configure cupsd.conf, open up http://localhost:631 and configure 
the printer in the CUPS interface. Now whenever I want to print, I see 
that the selfsame printer is added again, and CUPS mentions it as "added 
by HAL".

Is there a way to stop this sort of behaviour?

Cheers,

Niki
