Tenho duas impressoras, uma Dell V715w e uma HP LaserJet P2015, conectadas por USB a um computador com Ubuntu para compartilhar em todos os laptops da minha casa com o CUPS. Instalei ambas as impressoras localmente no computador Ubuntu, configurei o CUPS, iniciei-o e testei a impressão localmente, sem problemas.
Conectei-me à impressora HP em todos os laptops e testei a impressão de todos eles, também sem problemas.
Eu tentei conectar-me à impressora Dell em dois dos quatro laptops, executando o Vista, sem sucesso. Erros com:
Windows cannot connect to the printer. Make sure that you have typed the name correctly, and the printer is connected to the network.
A impressora Dell possui rede sem fio embutida, mas eu preferiria usar USB. Tenho quase certeza de que o instalei corretamente, porque ele imprime, mas não na rede. O computador "servidor" e um dos laptops que eu experimentei estão diretamente conectados ao meu roteador sem fio através de Ethernet. Há algo que possa estar causando problemas?
