Tengo una impresora Epson Workforce 845. Lo tengo configurado correctamente en mi red inalámbrica. Puedo imprimir en él sin problemas desde un par de computadoras con Windows diferentes, pero solo tengo éxito intermitente en mi Mac. Por lo general, cuando voy a imprimir en la cola de impresión, dice "Buscando impresora". luego "La impresora no está conectada".
He intentado reiniciar el sistema de impresión, reinstalando los controladores de Apple y epson. nada funciona.
Mi impresora está en una ip estática 192.168.0.65. La hoja de confirmación de configuración de red impresa por la impresora lo confirma. Si hago ping a esa dirección desde mi mac, a veces tiene éxito y a veces da el error ping: sendto: Host is down Request timeout for icmp_seq 0 . No soy profesional en la línea de comandos, pero probé nmap -A 192.168.0.1/24 y esta es la sección relevante

Algunas veces, al azar, puedo imprimir una o dos veces desde mi mac, pero los trabajos de impresión posteriores fallan. Además, después de reiniciar el sistema de impresión, a veces la impresora no aparece en el cuadro de diálogo Agregar impresora.
EDITAR:
Cuando la impresora deja de funcionar para mí e intento abrir la Utilidad de impresora Epson, no se abrirá. A pesar de que todos los demás pueden seguir imprimiendo, pude imprimir cuando lo intenté 15 minutos antes. Aunque dice que no puede encontrar la impresora, en Preferencias del sistema puedo ver el cambio de la impresora de "Inactivo" a "En uso" y viceversa.
¿Puede alguien ayudarme con una solución o una forma de diagnosticar qué está mal? Gracias!
