1、Java實現(xiàn)打印功能用java實現(xiàn)打印，java.awt中提供了一些打印的API,要實現(xiàn)打印，首先要獲得打印對象，然后繼承Printable實現(xiàn)接口方法print,以便打印機進行打印，最后用用Graphics2D直接輸出直接輸出。下面代碼實現(xiàn)了簡單的打印功能：importjava.awt.BasicStroke;importjava.awt.Color;importjava.awt.Component;importjava.awt.Font;importjava.awt.Graphics;importjava.awt.Graphics2D;importjava.awt.lmage;import

11、(e.printStackTrace();這個例子實現(xiàn)了打印字符申，線包括虛線和打印圖片。而且通過Paper的setImageableArea可以設(shè)置打印的區(qū)域和邊距，讓開發(fā)者隨意的設(shè)置打印的位置。下面的打印代碼沒有設(shè)置打印區(qū)域，默認為打印紙張的區(qū)域和邊距，比方我們一股用的A4紙，打印的起點X和Y坐標那么是72,72。無區(qū)域設(shè)置的代碼：importjava.awt.BasicStroke;importjava.awt.Color;importjava.awt.Component;importjava.awt.Font;importjava.awt.Graphics;importjava.awt
