AirPrint for iOS Devices

For those of you who couldn't wait and installed the 4.2 update on your Apple iOS device and want to do the AirPrinting thing, I found this article's suggestions to be the most useful.

Following the instructions, step-by-step, I was able to make my 4.2 iPad print to my networked HP laser printer shared by both my MacBook Pro AND my Mac Mini Server.  If using the printer to share, make sure that you not only add the printer from the System Preferences, but you'll then need to make sure it's shared out with Bonjour in the Server Administrator under Print

Incidentally, the AirPrint works GREAT!  Of course it requires application support from the appropriate app that you're using but most of what I'd ever want to print is from within the Apple Mail and Safari apps.  I'm sure the functionality will be added to most of the applicable 3rd party apps soon if they don't have it already.

Excerpt from the page below (you'll need to refer back to it to download the zip file containing the requisite printer files).

Step 1: Download Mac OS X to latest version and update your system.

Step 2: Download the AirPrint Activation Package containing three files and unzip it. (download link at the bottom of this post)

Step 3: Copy the urftopdf file to

/usr/libexec/cups/filter/urftopdf

Step 4: Copy the files in mime folder to

/usr/share/cups/mime/apple.convs
/usr/share/cups/mime/apple.types

Step 5: Delete your existing printer if you installed any.

Step 6: Reboot the system.

Step 7: Re-add the printers and enable the printer sharing funtion.

Step 8: Now if you have updated your iDevice to iOS 4.2 GM release, you can print any document or picture by giving a print command
