It depends on the Operating System. Python doesn't have a standard,
system-independent way to print to paper.
On most Unix-like systems (like my MacOS) the following works:
from subprocess import Popen, PIPE
p = Popen('lpr', stdin=PIPE)
p.communicate(b'Hello World')
p.stdin.close()
p.wait()
In a production system error checking should be added. Also if a nice layout is
desired, you should probably want to generate a PDF file and send that to the
printer, possibly with the use of LaTeX.
