Command.PRINT_AND_WAKE_PAPER_BY_LNCH
打印并走纸value点行
Command.PRINT_AND_WAKE_PAPER_BY_LINE
打印并走纸value字符行
Command.ALIGN 设置打印内容位置，Value值可指定设置的具体位置，可以为
Command.ALIGN_LEFT;
Command.ALIGN_CENTER;
Command.ALIGN_RIGHT
例1：设置打印文本居中
Printer.setPrinter(Command.ALIGN, Command.ALIGN_CENTER);
Printer.printText("hello world!\n");
例2：设置打印一维码居中
Printer.setPrinter(Command.ALIGN, Command.ALIGN_CENTER);
Printer.printBarCode(BarcodeType.CODE128, 2, 150, 2,"123456");
例3：设置打印二维码居中
Printer.setPrinter(Command.ALIGN, Command.ALIGN_CENTER);
Printer.printBarCode(BarcodeType.QRCODE, 2, 3, 6,"123456");
注：以上居中对于打印图片printImage方法无效
