Java调用热敏打印机

本人使用的是佳博GB-58L打印机

// 通俗理解就是书、文档
Book book = new Book();

// 打印格式
PageFormat pf = new PageFormat();
pf.setOrientation(PageFormat.PORTRAIT);

// 通过Paper设置页面的空白边距和可打印区域。必须与实际打印纸张大小相符。
Paper p = new Paper();
p.setSize(165, height); // 纸张大小A4纸(595, 842),经测试58mm为165
p.setImageableArea(5, 5, 155, height + 20); //设置打印区域，A4纸的默认X,Y边距是72
pf.setPaper(p);

// 把 PageFormat 和 Printable 添加到书中，组成一个页面
book.append(new PrintUtil(), pf);

// 获取打印服务对象
PrinterJob job = PrinterJob.getPrinterJob();
job.setPageable(book);
try {
job.print();
} catch (PrinterException e) {
System.out.println("================打印出现异常");
}

}

}以上为工具类
下面是调用的代码
