Hello Mr. Mutaku,

Thanks for the code on printer selection on tkinter .I manage to change the command module which you imported to subprocess after reading about it. Found it been changed to subprocess in python 3.6 version .Have run the script but what i got as an output is gui with two labels and buttons. I was expecting to get something like what you get in microsoft word when you click on print button ,which displays printer lists you've installed on your machine for you to print through.

I would be grateful if you can modify the code or direct me to a link which i can get how to do printer selection in tkinter . Have attached two images named Mr.Mutaka script and Expecting result.

Best regards.
