Printer share

I have a Dell Mini-tower(XP Home) attached to a HP all-in-one printer. I recently bought a Linksys wireless router to accompany a new Dell Inspiron(XP Media). I set up sharing my printer on the 1st Dell and named the printer. When I connected the laptop to my router for interent connection all is well. I connected to the printer for 10 minutes. After that I suddenly cannot see or reconnect to the printer again. Any thoughts or ideas? Many thanks!

did you allow printer sharing on the machine to which the printer is attached? Also check your firewall.

I did allow sharing of the printer on the computer to which the printer is attached. I will check on the firewall. Many thanks!

Is it working now?
