Goal

I'm a lazy person so I wanted to find a way to automate printing out my code, without having to put it into a word document and risk losing the formatting.

Challenges

I did not face any challenges with this, I just typed it up in the space of about 2 minutes. Really, the most difficult part was converting it to a binary file.

Breakdown

The first two lines denote the file name, version number, and the author (me).

# homeprint.py Eins Null
# Made by William "Vulcan" McDonald.

The next set of lines import the packages required: subprocess and os.

import subprocess
from subprocess import call
import os
from os import path

The variable 'printer' is defined with the address, either by hostname or IP.

# Change value to your printer's hostname of IP address
printer = '192.168.7.85'

It then starts an infinite loop to retrieve file and determine if the file exists. If the file does not exist, inform user and collect file again.

while True:
  file = raw_input("Where is your file? ")
  if (path.isfile(file)):
    break
  else:
    print("File " + file + " does not exist.")

Finally, it calls the command to send the file to the print cache.

call(['lp', '-d', printer, file])
