Example of how to use, same way as how you are using it. I would recommend to place everything inside a ‘Mutable buffer’
How I would use mutable buffer:
import {MutableBuffer} from 'mutable-buffer';
buff=new MutableBuffer();
this.buff.write(CMD.TEXT_FORMAT.TXT_ALIGN_CT);
this.buff.write(CMD.TEXT_FORMAT.TXT_BOLD_ON);
this.buff.write(CMD.TEXT_FORMAT.TXT_NORMAL);
this.buff.write(CMD.TEXT_FORMAT.TXT_FONT_A);
this.buff.write(CMD.TEXT_FORMAT.TXT_BOLD_ON);
this.buff.write("Razman is super awesome dude");
this.buff.write(CMD.FEED_CONTROL_SEQUENCES.CTL_LF);
this.buff.write(CMD.TEXT_FORMAT.TXT_BOLD_OFF);
this.buff.write(CMD.TEXT_FORMAT.TXT_BOLD_OFF);
this.buff.write(CMD.TEXT_FORMAT.TXT_FONT_A);
this.buff.write("Yes he is really awesome");
this.buff.write(CMD.FEED_CONTROL_SEQUENCES.CTL_LF); //2 lines
this.buff.write(CMD.FEED_CONTROL_SEQUENCES.CTL_LF);
//and finally, send this.buff to printer
this.connectBT(address)
.subscribe(item_printer=>{
this.bt_serial.write(this.buff.buffer)
.then(dataz=>{
console.log("WRITE SUCCESS",dataz);
this.buff.clear();
this.disconnectPrinter();
});
},err=>{
console.log("ERROR",err);
this.buff.clear();
this.disconnectPrinter();
})
Hope that helps
Could you help me please.
