Tkinter doesn't wrap native printing API's. There are a few extensions that
do it, but they are platform specific and not complete.
The usual ways of printing are like this:
1. If you're outputting data from the text widget, write that to a temporary
text file and print via lpr.
2. If you're outputting data from the canvas, write that to a temporary
postscript file and print via lpr.
This is on Unix/MacOS. Not sure what the equivalent API on Windows is.

Thanx Kevin.
Anybody can throw light on how to do the same in Windows ?

The conventional --crude-- way is to take the bitmap of a
window and to stretchDIBBitBlt it onto the printer device in windows
and osx. Native printer dialogs do exist for both platforms ...
When you do not need a printer dialog:
Convert the Tk-GUI to SVG, then wrap it into a fo-xml wrapper
--fo accepts inline SVG-- and use fop for printing.
This approach works cross-platform, albeit you need a Java
intallation (fop is a Java application).
You can use http://jeszra.sourceforge.net to generate SVG for a complete
Tk-GUI.
In addition. there is a python/tkinter SVG export project for the Tk canvas
--search the tkinter wiki.
