All-in-one network attached printer?

Hello all,

I'm looking to buy an all-in-one printer for a home network and am looking for some recommendations. It should be a laser printer (preferably with fax/scanner/copier built in) and needs to be able to attach to our home network.

Does something like this exist with a wireless connection or will it have to be hardwired?

Are there any websites or stores you would recommend looking at?

Thank you!
