Yo uso esta funcion para poder imprimir en matriz de puntos, tuve que hacer algunas modificaciones pero nada del otro mundo, antes genero el informe en un plano y despues lo envia a impresora, sin ningun problema, hasta me di el gusto de ajustarlo para que lo hiciera a impresoras remotas en una red de windows XP (captura el puerto, lo envia a imprimir y despues lo descaptura)
