A modo de cuaderno de bitácora publico aqui una configuración de CUPS que me dió muchos problemas, y muchos rompimientos de cabeza, para que tenerla siempre a mano. La información la he obtenido de aqui, y el problema venia por una configuración de los mimetypes de cups que me impedía imprimir desde una máquina windows en un servidor CUPS en Linux:
- Los trabajos eran procesados en los equipos windows pero no llegaban al servidor linux
- Los trabajos se quedaban en la cola de impresión del cliente, dando un error sin ningún tipo de información adicional
- La impresora está ocupada, inténtelo de nuevo en 10 segundos
Para solucionar este problema, en el archivo /etc/cups/mime.convs hay que descomentar la línea :
application/vnd.cups-raw |
Y en el archivo /etc/cups/mime.types hay que descomentar la línea:
application/octet-stream |
Y por último este es el código completo del archivo /etc/cups/cupsd.conf correspondiente a openSuse 11.1
