te mando un codio que uizas te ayude un poco a imprimir puesto que todos saben que esto no es facil en java y menos cuando hablamos de java.

si no entiendes me puedes escribir y te lo explicare mas detalladamente.

import java.awt.*;
import java.awt.font.*;
import java.awt.geom.*;
import java.awt.print.*;
import java.text.*;

// The PrintText application expands on the
// PrintExample application in that it images
// text on to the single page printed.
public class PrintText implements Printable {
//The text to be printed.
private static final String mText =
"Four score and seven years ago our fathers brought forth on this "
+ "continent a new nation, conceived in liberty and dedicated to the "
+ "proposition that all men are created equal. Now we are engaged in "
+ "a great civil war, testing whether that nation or any nation so "
+ "conceived and so dedicated can long endure. We are met on a great "
+ "battlefield of that war. We have come to dedicate a portion of "
+ "that field as a final resting-place for those who here gave their "
+ "lives that that nation might live. It is altogether fitting and "
+ "proper that we should do this. But in a larger sense, we cannot "
+ "dedicate, we cannot consecrate, we cannot hallow this ground. "
+ "The brave men, living and dead who struggled here have consecrated "
+ "it far above our poor power to add or detract. The world will "
+ "little note nor long remember what we say here, but it can never "
+ "forget what they did here. It is for us the living rather to be "
+ "dedicated here to the unfinished work which they who fought here "
+ "have thus far so nobly advanced. It is rather for us to be here "
+ "dedicated to the great task remaining before us--that from these "
+ "honored dead we take increased devotion to that cause for which "
+ "they gave the last full measure of devotion--that we here highly "
+ "resolve that these dead shall not have died in vain, that this "
+ "nation under God shall have a new birth of freedom, and that "
+ "government of the people, by the people, for the people shall "
+ "not perish from the earth.";
