Earlier today we reported that AirPrint is sort of shaky. It seems to be working for some people but not others. Developer Steven Troughton-Smith has come up with a method to get AirPrint working on all Macs running Mac OS 10.6.5. This is what you do: “The files you need are: If you migrate those from a 10.6.5 prerelease build (there seem to be many floating around torrent sites and file sharing sites – build 10H542 works; naturally I can’t link you to the files themselves, sorry!) to your machine you’re just one step away from having AirPrint working. The final key thing is you have to remove and re-add your printer in the Print & Fax preferences pane. Once you do that (and share your printer in the Sharing preferences pane) it should show up on any iOS devices that support AirPrint.” /usr is a hidden directory on your Macintosh HD (or whatever you call it) and you’ll need to access it via command line. If you’re not sure how to do this, hit up the instructions after the break. Be sure to backup the files you are replacing with this how to. Click here to download the files you need! Thanks, Chuck. How to access the /usr directory: Method 1: From the Terminal, type Method 2: From Finder’s “Go” menu, select “Go to folder…”. That’ll bring up a window in which you can type “/usr/libexec/cups”.
