Agree. Great if specific printers have built in software(ala airplay etc) for AirPrint.
BUT, seem like a better explaination is needed for somethings, perhaps I missed it in the article, but just wasn't clear to me, if so, I apologize.
What if the printer is networked(hard or wireless),
What if the printer is hooked directly to a PC.
Is this all Bonjour?
