É necessário para nossos testes uma impressora USB, PARALELA ou de REDE.
No exemplo a seguir tenho uma HP LaserJet Professional P1102w, HP Laser com rede sem fio, nela está configurado o IP 11.11.11.122.

Instalação:

aptitude update
apt-get install cups samba printer-driver-hpijs printer-driver-hpcups

vim /etc/cups/cupsd.conf

Agora reinicie o serviço:

$ sudo /etc/init.d/cups restart

Faça um teste para ver se esta tudo correndo bem.

No exemplo abaixo eu coloco o IP da minha rede, altere conforme a sua.

http://11.11.11.122:631

Configuração do samba:

Aqui fica a parte muito importante, geralmente muitas pessoas recebem um erro de “Acesso Negado: Não foi possível estabelecer uma conexão”. Elas conseguem instalar a impressora, mas não é possível imprimir por acesso negado. Vamos resolver esse probleminha.

Instalação manual de impressoras:

Uma outra forma de detectar e configurar impressoras com o Cups é necessáio utilizar o utilitário do pacote hplip

hp-setup -i
