Mac OS 10.6.5 and the AirPrint controversy (Update: hack it to work)

Yesterday Apple released Mac OS 10.6.5 via Software update. The update includes the usual raft of improvements and bug fixes, but it's what isn't in 10.6.5 -- namely AirPrint -- that's raising some eyebrows.

AirPrint automatically finds printers on local networks and allows you to print wirelessly over Wi-Fi without installing software. AirPrint requires a compatible printer or sharing a printer with a Mac running 10.6.5. You’ll see the dialog in Safari, Mail, and a handful of other native apps.

From the Apple press release:

AirPrint is Apple’s powerful new printing architecture that matches the simplicity of iOS—no set up, no configuration, no printer drivers and no software to download... iPad, iPhone and iPod touch users can simply tap to print their documents or photos wirelessly to an HP ePrint printer or to a printer shared on a Mac or PC.

Apple announced the feature at its iPod media event in September saying that it would roll out to iOS devices in November. New information indicates that shared printer support may have been dropped -- taking away a major AirPrint feature that was previously promised.

Developers report that all AirPrint references were recently removed from seed notes, the iOS 4.2 features page, and from Apple's iOS developer documentation. MacRumors notes that AirPrint is not working from devices running the iOS 4.2 GM seed to printers shared via Macs running 10.6.5.

But don't panic. Steve Jobs tells a MacRumors forum member that "AirPrint has not been pulled. Don't believe everything you read"

Let's hope that Apple quickly releases updates to both Mac OS 10.6.5 and iOS 4.2 with full AirPrint (and AirPlay) support.

Update: Ars Technica reports that Developer Steven Troughton-Smith found a way to reenable shared printer support.
