I just tested my first wireless printer (a Brother HL-2170w laser) and I'm loving it.
I put it in the corner, it prints. I put it in a closet, it prints. I stick it in an entirely different room, it prints. I'm sold.
If you want to get in on this wireless action yourself, Circuit City has the Lexmark Z1480 Wireless Color Inkjet Printer for a ridiculously low $29.99 (after a fairly substantial $50 mail-in rebate).
There are no crazy shipping charges either, though you'll likely pay sales tax.
The Z1480 includes both USB and 802.11g interfaces and supports Windows and Mac systems. It's a dual-cartridge printer that promises color output at resolutions up to 4800x1200 dpi. Basically, it's an entry-level inkjet that just happens to support Wi-Fi printing. Trust me, once you cut that USB cord, you'll never go back.
The rebate deal ends Saturday.
