# Enable / Disable network printer discovery.
# Use a boolean to enable or disable. A checked box will disable
# network printer discovery and an unchecked one will enable it.
# As a side effect all network printers previously found are removed
# and any you want, have to be added manually.
# Log out or restart if changes don't take immediate effect.
#
# Attempted solutions that proved insufficient:
# 1. Disable fx. BrowseProtocols in /etc/cups/cupsd.conf AND
# /etc/cups/cups-browsed.conf
# 2. Completely disable cups-browsed: systemctl mask cups-browsed

Beskrivelse

Fjerner alle printere, der automatisk er fundet via netværket. Derefter kan en printer så eventuelt tilføjes manuelt via enten scriptet “Printer - Tilføj netværksprinter” eller “Printer - Tilføj netværksprinter (PPD-fil skal angives)”.

Hvis I udelukkende bruger Princh skal I installere via scriptet “Installer Princh Cloud Printer”.

Hvis det ikke tager effekt med det samme, foreslås det at genstarte maskinen, efter scriptet er kørt.

Dette script er blevet testet og virker på Ubuntu 22.04.
