Java - imprimir JTable

Hola:

He desarrollado una pequeña aplicación que imprime un componente JTable con unos listados. Para imprimir, utilizo un contexto gráfico Graphics2D. El problema es que cuando mando imprimir tarda muchísimo en empezar a imprimir la impresora. Creo que se debe a que utilizo el contexto gráfico. Alguien sabría como acelerar la impresión o algún otro método para imprimir el listado?

Gracias

Hola!
Yo quisiera pedirte un favor, esque yo tambien tengo que imprimir unas tablas y no se ni por donde empezar. Por favor te agradeceria si me explicaras por encima como se hace o algun tutorial.
Gracias!
