Print to standard printer from Python?

Unfortunately, there is no standard way to print using Python on all platforms. So you'll need to write your own wrapper function to print.

You need to detect the OS your program is running on, then:

For Linux -

import subprocess
lpr =  subprocess.Popen("/usr/bin/lpr", stdin=subprocess.PIPE)
lpr.stdin.write(your_data_here)

For Windows: http://timgolden.me.uk/python/win32_how_do_i/print.html

How do I print to the OS's default printer in Python 3 (cross platform)?

This has only been tested on Windows:

You can do the following:

import os

os.startfile("C:/Users/TestFile.txt", "print")

This will start the file, in its default opener, with the verb 'print', which will print to your default printer.Only requires the os module which comes with the standard library
