I have sent you a new version to try out, can you also please send me the debug.log when you have an attempt. I have put in some more debug information on this version.
@Paul Can you see if if you have a logfile located in `T:Airprint/debug.log`. You must do the search again and when it stops working you can copy and send it to me. I might then see what is happening.
Thanx for testing, I am preparing a new version where the issue you see should be fixed. I got some time off for programming this weekend and next week so hopefully it will improve!
