Som standard kräver installation av skrivare på macOS att användarna är administratörer. Den här standardinställningen styrs av principinställningarna i /etc/cups/cupsd.conf
och kan ändras.
Om användarnas enheter hanteras av en MDM-lösning som Intune eller jamf kan du använda ett skript för att uppdatera filen och ta bort administratörsbehörigheter från auktoriseringsprincipen. Se exempelskriptet nedan.
Instruktioner

Uppdatera direktivet på rad 75 för att ta bortCUPS-Add-Modify-Printer

Exempelfil
Om du inte har ändrat cupsd.conf
filen på andra sätt kan du kopiera/klistra in innehållet exakt. Annars fungerar det som en referens. Den ursprungliga filen finns också nedan, för jämförelse.
