Return AirPrint Sharing To Mac OS X 10.6.5
Steven Troughton-Smith found a way to make printer sharing work on 10.6.5, but you’ll need an old developer version of the OS to enable it:
The files you need are:
/usr/libexec/cups/filter/urftopdf
/usr/share/cups/mime/apple.convs
/usr/share/cups/mime/apple.types
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.
