Ola pessoal
estou com o mesmo problema lexmark z 645 no ubuntu 10.04
mas no meu caso o sistema reconhece a serie 640 parece que esra tudo certo porem não imprime
fui guia ajuda e solicita habilitar depuração do escalonador CUPS
depois de depurado não imprime folha teste e mostra uma saida de diagnostico (avançado) notificando que não ha solução obvia
listando isto ( ai vai)
