How to disable auto-identifying pritners and auto-installing printer drivers?
Or at least to set CUPS to ask before installing anything?
Thanks!

There's no "ask first" option afaik. Usually it's cups-browsed that creates queues for everything it finds on the network, so start there:

sudo systemctl disable --now cups-browsed

If you want to keep it running, set CreateIPPPrinterQueues No in /etc/cups/cups-browsed.conf instead.

For USB printers it's usually not CUPS but the udev rule from system-config-printer (on Debian/Ubuntu it's the system-config-printer-udev package), removing that stops it.

Driverless printers will still show up in the print dialogs, but those are temporary queues, nothing gets installed.
