该博客展示了如何在Java中实现代码段的打印功能，包括创建Printable接口的实现类，设置字体、颜色，以及调用PrinterJob进行打印。同时，博客还涉及到查找和选择特定打印机，如EPSON TM-U220 Receipt，并使用JRPrintServiceExporter进行报表打印。

JAVA 打印范例：

import java.awt.print.PrinterJob;
import java.awt.print.Book;
import java.awt.print.Printable;
import java.awt.Graphics;
import java.awt.print.PageFormat;
import java.awt.print.PrinterException;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import java.awt.Graphics2D;
import java.awt.Color;
import java.awt.Font;
import javax.print.attribute.HashAttributeSet;
import javax.print.attribute.standard.PrinterName;
public class MyPrintTest
implements Printable
{
public int print(Graphics graphics, PageFormat pageFormat, int pageIndex)
throws PrinterException
{
Graphics2D g2 = (Graphics2D) graphics;
g2.setPaint(Color.black);
g2.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
Font font = new Font("宋体", Font.BOLD, 10);
g2.setFont(font);
g2.drawString("afasdfad", 10, 10);
font = new Font("黑体", Font.ITALIC, 18);
g2.setFont(font);
g2.drawString("第二行:", 10, 40);
return Printable.PAGE_EXISTS;
}
public static void main(String[] args)
{
MyPrintTest myprinttest = new MyPrintTest();
myprinttest.print();
}
public void print()
{
PrinterJob printerJob = PrinterJob.getPrinterJob();
Book book = new Book();
book.append(new MyPrintTest(), printerJob.defaultPage());
printerJob.setPageable(book);
HashAttributeSet hs = new HashAttributeSet();
String printerName="EPSON TM-U220 Receipt";
hs.add(new PrinterName(printerName,null));
PrintService[] pss = PrintServiceLookup.lookupPrintServices(null, hs);
if(pss.length==0)
{
System.out.println("无法找到打印机:"+printerName);
return ;
}
try
{
printerJob.setPrintService(pss[0]);
printerJob.print();
}
catch (PrinterException ex)
{
System.out.println(ex.getMessage());
}
}
}

Jasperreport指定打印机：

PrintService[] pss = PrinterJob.lookupPrintServices();
PrintService ps = null;
for (int i = 0; i < PSs.length; i++) {
String sps = PSs[i].toString();
//如果打印机名称相同
if(sps.equalsIgnoreCase("Win32 Printer : pdfFactory Pro")){
ps = PSs[i];
}
}
JRAbstractExporter je = new JRPrintServiceExporter();
je.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
//设置指定打印机
je.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE, ps);
je.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, false);
je.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, false);
//打印
je.exportReport();
