creating a hard copy

Hi,

I created a custom screen for my users, and I would like to give them the option of printing a hard copy of the information on the screen. I basically want to create a button that, when pushed, will perform the exact same function as when you go to the layout menu and select "hard copy". My users don't use the layout menu, so I'd like to make this easier by giving them a button right on the screen. What code do I need to use when my button's function is called to get the hard copy to print? I know how to set up the button, just not how to code for the print.

Thanks,

April King
