Printing in Python

[uri bushey]

So I have a tkinter based little program in Python that has a canvas 
loaded with a WaveSurfer (http://www.speech.kth.se/wavesurfer/) widget.

I am trying to print the contents of the WaveSurfer canvas. Is there an 
easy way to do this in Python? Also, I can pretty easily use the 
WaveSurfer "print" function in my program, but taht only prints to a 
PostScript printer or prints out a PostScript file.

I would like to automate the process of printing the PostScript file in 
a manner that is not terribly unwieldy and as transparent to the user as 
possible. Is this possible?

Thanks!
