蓝牙串口打印机模块使用说明
微型串口打印机内嵌蓝牙打印机模块，实现蓝牙设备、上位机PC、笔记本或PDA等通过蓝牙实现无线打印，原串口打印机无需关心蓝牙协议，应用简单，可靠稳定。
1、工作模式示意图：
2、工作模式说明：
A、打印机工作在从模式
加电后，打印机蓝牙模块工作在从模式，处于等待配对、连接状态。
主端设备查找、配对蓝牙打印机，配对成功后，即可向蓝牙打印机发起连接。
连接成功后，主端设备串口（或虚拟串口）与蓝牙打印机UART口形成透明传输，可以开始打印。
打印完成，主端设备断开蓝牙链路。
串口打印机忙时，可通过RTS向蓝牙模块的CTS引脚发送高电平，蓝牙模块检测到CTS脚的高电平后，停止向打印机发送数据，直至打印机将CTS置低。
B、打印机工作在主模式
打印机蓝牙模块预先绑定上位机蓝牙设备地址，双方PIN码一致。
加电后，打印机蓝牙模块工作在主模式，自动连接绑定的设备。
连接成功后，主端设备串口（或虚拟串口）与蓝牙打印机UART口形成透明传输，可以开始打印。
打印完成，可始终保持蓝牙链路，随时进行打印，如需断开蓝牙，关闭打印机模块电源。
串口打印机忙时，可通过打印机的BUSY脚向蓝牙模块的CTS引脚发送高电平，蓝牙模块检测到CTS脚的高电平后，停止向打印机发送数据，直至打印机将CTS置低。
C、灵活转换打印机工作模式
用户可通过AT指令，灵活设定蓝牙打印机的工作模式、串口参数。
可定制专用的蓝牙模块功能，如：用拨码开关控制打印机工作模式。
可定制专用的蓝牙模块功能，如：用拨码开关控制打印机的串口参数。
可定制专用的蓝牙模块功能，如：用拨码开关控制蓝牙打印机是否可见，是否可被配对。
