do you realise that this wouldn't work if you got no print job ?? i.e. it always return OK status if you don't have any print job ??

The code below works. I have only some problems with the status. It seems not correspond with microsoft constante declaration. I'm still working.

It's certainly not the best way to code...
so comments are welcome and thanks for people who will help me to become better ;-)
