currently i am using this small code and its working. i want to add more text and qr code on single print.this code is printing value qr code.

let printData="SIZE 4,4\nGAP 0.12,0\nCLS\nQRCODE 10,10,H,4,A,0,\""+this.value+"\"\nPRINT 1,1\n0d0a"

    let xyz=this.connectBT(address).subscribe(data=>{
      this.btSerial.write(printData).then(dataz=>{
        console.log("WRITE SUCCESS",dataz);

        let mno=this.alertCtrl.create({
          title:"Print SUCCESS!",
          buttons:['Dismiss']
        });
        mno.present();

        xyz.unsubscribe();
      },errx=>{
        console.log("WRITE FAILED",errx);
        let mno=this.alertCtrl.create({
          title:"ERROR "+errx,
          buttons:['Dismiss']
        });
        mno.present();
      });
      },err=>{
        console.log("CONNECTION ERROR",err);
        let mno=this.alertCtrl.create({
          title:"ERROR "+err,
          buttons:['Dismiss']
