android 蓝牙打印机(ESC/POS 热敏打印机),打印菜单小票和图片,对蓝牙配对和连接打印功能进行了封装,让你超快实现蓝牙打印功能。
有时候发现连接蓝牙时总是连接失败,跟踪代码发现是在BtService中mmSocket.connect()一直抛出异常。bt socket connect failed,然后提示连接失败需要重启蓝牙。有什么解决方法吗?
图片出来是一堆乱码, 这个有人遇到吗?
/**
* 字体变大为标准的n倍
*
* @param num 倍数
* @return bytes for this command
*/
@SuppressWarnings("unused")
public static byte[] fontSizeSetBig(int num) {
byte realSize = 0;
switch (num) {
case 0:
realSize = 0;
break;
case 1:
realSize = 17;
我想用在公司的app上,得评估一下。
楼主你好,请问一下如何监听打印是否成功,比方说没纸或者中间打印机故障了,如何判断是否已经打印成功了?
