iOS 4.2.1is available on iTunes. It is a lengthy process, but worth it.

Let us know if you've experienced any issues.

1. Printing is limited to AirPrint compatible HP models.

WTF, Apple?

[alfredo]

2. I'm sure it will expand over time. Remember iTunes didn't

have many publishers at first.

3. Right, but it's seeming to require this proprietary hardware

I'd prefer to use the wi-fi compatible printer I already have, rather than buy another $100 to $150 printer just to use with the iPad/iPod. But that's our boy Steve, always moving away from compatibility.

Unless they integrate a wi-fi option (which seems like the obvious first choice), even some retrofit box is going to cost at least $50 and probably still not be fully compatible.

Plus, the few reviews I've seen of these HP printers have been bad.

4. I have a dead hp sitting on my desk right now.

I have tried to get multitasking to work, but it isn't activating.

5. From what I have read, Apple is pushing driverless printing.

6. A couple things and a couple solutions

There has been a rumor sited to several sources that Apple had to drop the shared printer AirPrint do to a patent squatter. It makes a lot of since.

You can still enable AirPrint via a very quick and easy hack (Mac and PC): http://mobiputing.com/2010/11/how-to-enable-airprint-for-mac-or-windows-printers/

Here is a free 10.6 app that does it too: http://netputing.com/2010/11/21/airprint-hacktivator-v1-6/
