After painstakingly installing printer drivers for a thermal printer at work I realized I still don’t truly understand what I was installing. (Bonus points if you can cover video card drivers too cause idk what drivers are In that sense either)

In order to print, every program in windows will send a command like “print an A”. Its the same for notepad or internet explorer or word.
The problem is in order to be more flexible, every piece of hardware takes a different input to do a different job. So lets take the printer. In order for that printer to print an “A” it needs to receive 011010101 for instance.
The problem is this other printer needs to receive the command 010101100110 to print an A.
So each hardware manufactuer makes a driver, so all any program has to do is tell the driver to “Print an A” and then the correct driver will send the printer the correct command.
