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.
