Printing Elements

How do I print only certain things in my program?  Similairly to the print screen function.

Here's what I want to do:

I want to have a box with two text boxes inside of it.  All that I want to print is the lines of the box and the text that was typed.  I don't want to print the "background" of the program like the print screen function does.  I also don't want the box around the text box, and the white area of a text box to be printed.  I want them to be printed exactly as they are viewed on the screen.
