Not sure if you’ve found a solution. Windows 7 users need to download and install Bonjour Print Services Download Bonjour Print Services for Windows v2.0.2 (you don’t need iTunes) then check this link http://www.youtube.com/watch?v=ws9pV30Vfy8 which covers setting up connections for both Mac and PC. Was the simplest explanation I found. Your Mac or PC will need to be WiFi enabled. This has already proved very useful and I’d like to see more than the basic functionality offered in future versions. Great App!
