CUPS Não alcançando a impressora a menos que a impressora seja ligada e desligada

Question

Estou tendo um problema com minha impressora de rede, pois o CUPS parece não conseguir acessar a impressora, a menos que eu a desligue e ligue-a novamente. Tudo o que resta na fila de impressão será impresso após a reinicialização da impressora.

O software de digitalização (xsane) não tem esse problema, pois eu posso digitalizar a qualquer momento.

Answer 1

Parece que foi um fracasso na resolução de nomes. Corrigido pela atribuição estatica de um IP para a impressora e alterando as informações de conexão para o ip.

lpd: // BRW00234EA65E02 / BINARY_P1

para

lpd: // PRINTERIPADDRESS / BINARY_P1
