Tentem usar esse exemplo e adequar a sua necessidade:

//Inicio do código
import java.io.FileOutputStream;
import java.io.PrintStream;

public class Impressao {
public static void main(String[] args) {
FileOutputStream fos = null;
PrintStream ps = null;
try{ 
fos = new FileOutputStream("LPT1:");
} catch (Exception ex) {
}
try {
ps = new PrintStream(fos);
} catch (Exception exception) {
} 
ps.print("Coloque aqui o que você quer imprimir");

}
}
//Fim do código

Também recomendo dar uma lida nesse artigo, foi nele que encontrei esse exemplo:

Olá Landi20,

Você poderia dizer como conseguiu resolver seus problemas? A sua dúvida pode ser a mesma que a de outros usuários do fórum.

Obrigado.

this.jframe1.setvisible (true);
this.jframe1.setsize(800,400);
