Migración del servidor de impresión

Migración del servidor de impresión

  • El siguiente script permite migrar un servidor de impresión al servidor B con la siguiente:
  • Eliminación de las impresoras de la estación de trabajo que están asignadas al servidor anterior solo si están presentes en el nuevo
  • Cambiar la impresora predeterminada si es una impresora del servidor anterior.

Para poder seguir la ejecución del script, los seguimientos se escriben en el visor de eventos de Windows.

Requisito previo: las impresoras deben tener el mismo nombre en ambos servidores.
