Question about 1 Router, 1 Network Printer & 2 PCs

My first post so go easy on me :-)

I have 2 Pcs running windows vista & a linksys wag54gxvs wireless router + have just purchased a HP 5550n Laserjet printer.

What I want to do is connect my 2 pcs + printer all into the router via ethernet cables so both Pcs can access the printer. The 2 pcs are connected to the router via ethernet cables already & work fine. As it stands I have a USB printer which the host computer needs to be turned on to use the printer from the "2nd" computer. This isn't any use to me anymore & it would be much better the new way.

I have connected the printer to the router via an ethernet cable but my computer cannot find it. Do I need to do something? I have downloaded the drivers from HP for the printer & installed but they cannot find the printer either. I haven't tried using a USB lead to install the printer as you would a normal printer because I don't want it to work this way. I presume if I did then it will run off the PC fine.

Hope someone can give me a little pointer..

Thanks
