Java實(shí)現(xiàn)打印功能

1、-. z.Java實(shí)現(xiàn)打印功能用java實(shí)現(xiàn)打印，java.awt中提供了一些打印的API,要實(shí)現(xiàn)打印，首先要獲得打印對象，然后繼承Printable實(shí)現(xiàn)接口方法print，以便打印機(jī)進(jìn)展打印，最后用用Graphics2D直接輸出直接輸出。下面代碼實(shí)現(xiàn)了簡單的打印功能：importjava.awt.BasicStroke;importjava.awt.Color;importjava.awt.ponent;importjava.awt.Font;importjava.awt.Graphics;importjava.awt.Graphics2D;importjava.awt.Image;impo
