Ну так и быть...
Я понятия не имею почему не работает root (вроде как по умолчанию должен, тут вам чисто не повезло)))

И так начнём...
Открываете cupsd.conf, там есть
Стандартная политика, отредактировать надо её...

<Policy default>
правила
</Policy>

Если чего непонятно спрашивайте. Конкретный пункт.

p.s. после изменения желательно

# systemctl restart org.cups.cupsd.service

p.p.s. если вы хоть краем глаза глянули эти правила, увидели что для таких ограничений как CUPS-Add-Modify-Printer CUPS-Delete-Printer и др.
используется не конкретный пользователь, а массив @SYSTEM (конечно можно вместо него прописать своего пользователя или группу), но лучше просто добавить пользователя в него. Он формируется в файле /etc/cups/cups-files.conf SystemGroup.
