Printer drivers?!!!
I use an Epson whatever and have NEVER been able to get the wireless printing working due to it's request for a WEP password that despite deep googling, etc., I've never been able to find.
My point is not to find a solution here, but to point out that this is the weakest link in the chain of modern computing in my opinion.
I'm a veteran of 25 years of using Macs, 16 of them...and through the years the piece of hardware I've had the most problems with have been PRINTERS.
I wish Apple would make their own printer again....
