Oculta / remove impressoras de rede da caixa de diálogo de impressão

Question

Eu tenho quatro impressoras, se vou para o traço e, em seguida, impressoras. No entanto, se quando eu imprimir na caixa de diálogo, existem muitas impressoras (100?) Que aparecem e que eu nunca vi / instalei. Eu estou supondo que são impressoras de rede. Como posso removê-los ou impedi-los de aparecer?

Esse problema só começou a acontecer em 14.04.

meu arquivo /etc/cups/cupsd.conf está abaixo

Answer 1

1. Abra o Firefox ou qualquer navegador em: http://localhost:631/
2. guia Administrações → Em Título do servidor, Editar arquivo de configuração

3. Procure Browsing / BrowseLocalProtocols e defina-os para:

   Browsing Off
   BrowseLocalProtocols none
   

   depois, salve as alterações

4. Digite seu nome de usuário / senha, pronto

Se você preferir a linha de comando:

sudo nano /etc/cups/cupsd.conf

    

Answer 2

Acho que a melhor solução é desabilitar o uso de xícaras (isso evita a detecção automática, mas não o uso de outras impressoras remotas):

sudo gedit /etc/cups/cups-browsed.conf

e altere a linha de BrowseRemoteProtocols para:

BrowseRemoteProtocols none

, em seguida, reinicie o sistema (ou execute sudo service cups-browsed restart ).
