How to connect to printer in python?
Question
I've been to build a time card calculator for my sister to use at her job, and the only thing I have left to do on it is make the print button functional.
I have it set up so she can put in the name, pay period start and end, pay date, and all of the clock in and out times. it then adds everything together and puts it into a tkinter label, and puts the grand total of all shifts at the bottom.
I need to try and print all of the information out using the printer but im not sure what the best way is to make this function.
also, im writing the code on OS X, but she'll be using it on windows so I don't need it to be functional on mac.
