Most likely this message is displayed whenever printing fails. So, your issue might not be the same as mine.
I did a little playing around and found out can get additional info from the driver by running "airprint.exe" (you may need to stop the AirPrint service before running it). Extra info is printed to the airprint.exe console and in my case it turns out extra dialog boxes were being displayed for multi-page documents. These extra dialogs don't get displayed when run as a service.
Turned out the the problem was that "Double-sided" defaults to ON for AirPrint on iPad/iPhone. Since my printer doesn't automatically do double sided this causes extra dialog boxes to appear.
I was able to fix the problem for my printer by simply turning off "Double-sided" printing in the iPad/iPhone Printer Options screen.
