sorry, I am very bad at this, I basically copypasted some terminal commands from some tutorial (I think it was https://www.tomshardware.com/how-to/raspberry-pi-print-serve...) and also spent a lot of time fixing some of the settings (there had to be something done about spooling service) to finally make it work for my windows PC, as mac and iphone started working immediately. But even if a complete noob like me with some lame google-fu skills could do it, I think anyone can.
