Is printing from GUI still a 'not-happening' thing with Tkinter ? I
have just started learning it.

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.

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.
