Wireless Printing

Wondering if I could get some help.

I am trying to set up wireless printing using IP:

Macbook 10.6.2
Linksys 54wrtgs
Dell 1320c connected to the router via network cable

I have done a search and looked at the FAQs but cannot get it to work.

I have tried going to IP printer -> LPD printer, put address in, leaving queue blank and installing the dell driver.

I have also used L1 for queue with and without L1 for name (as suggessted on other forums)

Any other suggesstions?

Thanks
