[Tutor] How to get a Tkinter window to print a color copy of itself as a .pdf file?

I have very little experience with issuing print commands using a Unix
environment. Despite this, I wish to design a Tkinter window with a
"Print" button, which, when clicked, would create a copy of the
contents of the window as a .pdf file. GhostScript is available on my
systems.

I know that the Canvas container has the ability to print itself to a
postscript file, but I do not want to use Canvas as my container
object. So I am hopeful this is as simple as discovering the proper
command to associate with a button, which will generate a color
postscript file of the containing window. Once I can get that file, I
know how to get a .pdf out of it.

The main software that we use on these systems has this print command
associated with its color printer *button*:

lp -c -d ricoh -o resolution=1200 -o profile=photo -o dithering=photo
-o colorsettings=superfine -o black=k -o papper=letter -o itray=tray1

BTW, "papper" is what is actually in this software product's color
printer settings. But can this be correct? Anyway, it does print to
*paper*!

I suspect that some variant of this command associated with a print
button would print *something*, but how do I get it to print the
specific window containing the to-be-designed print button? Also, I
need it to print a postscript file, not print to paper. I suspect this
is another configuration setting that I need to research.

As always, many thanks in advance!
