How to Open and Print a File (In a Printer) using Python 3's Tkinter?

Question

Hello again to the Community! How can I open a LibreOffice or Word file (on my Mac, but eventually Windows as well) using Tkinter on Python 3. My UI has several buttons that I want to associate with a specific file, and when that button is pressed, it should send a command to a Brother printer and print that file out. While I am here, I'd also like to know whether there is a script to detect what OS the user is using and do separate commands (as Mac and Windows have different requirements) also using Tkinter. My code goes as follows.

Note: If you look at the function 'SignOut', it screws everything up. That is why it is commented.

You can use the platform module to detect the operating system. Like so:

import platform
print platform.system()
# Windows / Linux
if platform.system() == "Windows":
    # Do this
if platform.system() == "Linux":
    # Do this differently

You could use the command argument to create a callback for a tkinter.Button:

 new_button = Button(master, text = "Some button", command = function)

For the Word-documents, you can use python-docx, you can find the documentation here. Printing the file indeed needs to be done differently on different platforms. You can find that answer here.
