pearOS's System Settings has a full Printers page, but it's a front-end for CUPS (lpstat/lpadmin) - CUPS itself isn't installed by default on either build, so the page has nothing to talk to.

pearOS NiceC0re (Arch-based)

sudo pacman -S --needed cups cups-pdf system-config-printer
sudo systemctl enable --now cups.socket

For network/USB printers, most modern printers work out of the box with CUPS' "driverless" (IPP Everywhere/AirPrint) support once the service is running - just reopen Settings → Printers and add it.

pearOS Goldwing (Debian-based)

sudo apt update
sudo apt install cups printer-driver-all system-config-printer

CUPS enables itself automatically on Debian after install - no extra step needed.

After installing, reopen the Printers page in Settings (or run lpstat -p in a terminal to sanity-check CUPS is actually responding).
