Vinegar is the best. It replaces hostile video players like the one on YouTube with native HTML5 <video> elements so everything works as expected (like picture-in-picture).
Raspberry pi imager has an advanced menu that can be accessed with ctrl+shift+X. It allows you to configure a lot of settings to include networking before even installing the OS to the sd card.
I’ve run cups on a pi zero w for a while and it required the occasional restart, took quite a long time to load a job, and the margins were a nightmare to get right. Some of those issues may have had to do with the specific printer/drivers I use. I’ve since moved on.
