There's a pretty good node here: Printing in NT. One of the followups shows multiple ways to send output to a printer on Win32 (in the true spirit of Perl).

As for sending output to files, that's covered in perlintro, and is easier than fiddling with printers.

Beyond that, are you asking how to retrieve values from text boxes? We would need to know the type of framework you're using and probably see a bit of code to give a thorough answer on that topic.
