Andube investigando, y encontre este codigo en una pagina, el cual puedo modificar para hacer lo que necesito, pero la situacion es esta.
Si los datos que meten en el campo de texto son correctos, debe desbloquear la pantalla, hasta ahi no hay ningun problema, el problema es que de ahi usan una aplicacion hecha por un provedor y al final imprime una etiqueta, se puede saber cuando cambia el estado de impresion para que cuando imprima volver a bloquear la pantalla y que asi se este repitiendo?

Este es el codigo que encontre:
