You'll learn about ADHOC WIFI networking to get this to work. The only problem I run into is that many want this stuff to "just work." We're not there yet.
So yes, you can print to most wifi enabled printers but setup is mildly taxing.
I am looking to buy a new laser printer and am attracted to the notion of being able to print from my laptop (built-in wireless) without having to attach/detach a cable to it all the time. Is it possible to print to a wireless printer without having an existing network or router in place? I am looking at the brother HL-5370DWT or HL-2170W but am open to other suggestions. Thanks.
