Eu tenho uma Canon Laser Shot LBP6200d e estou executando o Ubuntu 16.04. A impressora não tinha um driver no banco de dados, portanto, instalei os drivers Linux de 64 bits do site da Canon e, uma vez que o fiz, o Linux identificou minha impressora. Primeiro, quando enviei arquivos para impressão, o status ficou completo, mesmo que o arquivo não tenha sido impresso. Depois disso, seguindo um guia, substituí o arquivo pdftops. Agora, quando eu imprimir qualquer coisa, o status é interrompido.
lpinfo -v dá isto:
network lpd
network beh
direct ccp
network socket
network https
network ipp
direct cnusb:/dev/usb/lp2
network ipps
network http
network ipp14
direct usb://Canon/LBP6200?serial=0000A1C4O8SI
direct hp
direct hpfax
Assim, posso ver que a impressora é reconhecida

Por fim, corri sudo usb_printerid /dev/usb/lp2 , pois a impressora estava conectada e recebi:
GET_DEVICE_ID string:
MFG:Canon;MDL:LBP6200;CMD:CAPT;VER:3.0;CLS:PRINTER;DES:Canon LBP6200
Portanto, fica bastante claro que a impressora foi instalada e reconhecida. Os drivers parecem estar funcionando e o sistema sabe o caminho correto para a impressora. (Tudo foi praticamente o mesmo antes de eu ter substituído pdftops ) Eu também sei que a impressora está funcionando porque funciona corretamente no Windows 10.
Se alguém pudesse me guiar, seria ótimo. Desde já, obrigado.
EDITAR:
Eu também corri tail -f /var/log/syslog com a impressora desconectada e, em seguida, enquanto ela estava em execução, conectei-a novamente. Esta é a saída que recebi depois que eu conectei a impressora:

Acredito que o erro está em algum lugar aqui, mas não consigo encontrá-lo.
