Suppressing the 'Printing...' popup

Hi all,

I am building an application which prints an individual bar code label each time an operator creates a production part.
I would like to suppress the popup message / window which tells the user the barcode (report) is being printed because it has no additional value in this case. On the contrary, it briefly blocks the user's view on the application window and because the production process is quite fast the 'Printing..' window is displayed hunderds of times a day which is really disturbing. The print itself is performed very quickly so the popup has no use at all.

Anyone ?

Thanks
Stefan
