Printers With Built-In WiFi Looking Good

Printers that can only use a parallel cable connection are needed but are limited. Enabling wireless printing is a way to add flexibility.
The Washington Post has a review of some options and writes
Printers often get left behind when WiFi comes to a home — the cables needed to link them to a PC may then wind up anchoring at least one computer to a desk. Printing from any other machine then involves fussing with printer sharing (always an adventure in Windows) or transferring individual files to the one machine wired to the printer.
Putting the printer itself on the wireless network ought to be an obvious remedy, allowing you to park the WiFi-enabled printer anywhere, then easily share it with every computer on the network.
