Printer on home network after range booster

I have a MacBook Pro running Lion. Previously I could print remotely from another room. I just added a range booster to my new Verizon modem/router and no matter whether I am on the main network or the new extended network (wifi), I cannot print anymore.

I am not finding a way to fix this. Any suggestions?

Thanks.

I have an HP Photosmart 7250 printer connected by ethernet to the modem and by USB to my desktop computer.

The modem/router is Verizon's Actiontec. The previous modem/router was the same kind, but I just got the newer version. The new one is plugged into the router with the same cable.

Thanks.
