Tricky Print Button Question

I am using Flash CS4 and AS3.

I have an interactive map which allows people to choose what layers they want on it, before printing their own version out. I intent to have a button (PrintUp) which prints the movieclips with the alpha state the user has chosen.

Here's the map I'm working on to help you understand:

The map area is 700x700.

Does anyone know how I'd go about doing this?

Thank you.

PrintJob class gets the job done, I guess. Never really tried it, because I've never been in a situation where I need it!
