我必须使用热敏打印机打印发票收据。 我用Zjiang Thermal printer打印收据。 他们还提供manual &演示项目。 在演示项目中,他们使用librts“btsdk.jar”来实现连接&打印。如何使用蓝牙热敏打印机打印发票收据
我已成功建立打印机& android设备之间的连接。 但是没有关于文本对齐(中心,左,右)&单元宽度,高度的指南。
I have try it。它只通过改变格式2变量来改变文本高度。
如何通过蓝牙打印机打印发票。
也请说明本条
byte[] cmd = new byte[3];
cmd[0] = 0x1b;
cmd[1] = 0x21;
cmd[2] |= 0x10;
CMD 2 - 用于更改字体高度 有什么用CMD [0] & CMD 1
代码发送印刷消息到蓝牙打印机演示项目
String msg = "";
byte[] cmd = new byte[3];
cmd[0] = 0x1b;
cmd[1] = 0x21;
cmd[2] |= 0x10;
mService.write(cmd);
mService.sendMessage("Congratulations!\n", "GBK");
cmd[2] &= 0xEF;
mService.write(cmd);
msg = " You have sucessfully created communications between your device and our bluetooth printer.\n\n"
+" the company is a high-tech enterprise which specializes" +
" in R&D,manufacturing,marketing of thermal printers and barcode scanners.\n\n";
mService.sendMessage(msg,"GBK");
