Wireless Printer Problems

[standingquiet]

I got a new wireless printer today and now having problems. Everything was fine at first my macbook found it in print/fax settings. Then where it says "Print Using" at the bottom of the "Add Printer" page i selected "AUTO" and the printer disappeared and wont find printer anymore.

I've restarted the Printer and Macbook but it still wont find the printer. Is there a way i can reset the printer settings?

Thanks

Matt
