I just corrected a bug with the Activation detection routine. The bug was reported in the support forum and would present itself in the inability to properly “deactivate” AirPrint.
Version 1.1.2 address this issue. I encourage everybody to upgrade to this release if you want to “deactivate” AirPrint.
As usual, you can grab a copy of the latest version on the main AirPrint Activator application page found here.
