# 1
I've managed to find some code that almost does what I need (silent print).
Below is the whole thing, it checks for mail every 3 minutes, when a new item arrives it sounds an audio alert and it displays the message content. With the inclusion of the Print2DPrinterJob class, it will now happily also prints "abc" on my default printer, without asking for confirmation of printer/settings (ie. silent).
I would be very grateful is someone could show me how instead of "abc" it prints the String "contents" (the email message content).
I know... I am guilty of patching together pieces of other peoples examples/tutorials without understanding how it works. I promise (!) I will study and learn to write my own in future, but for now I really need to get this working, so please assist if you can. thanks in advance.
