Not getting the whole data.

[RintuMondal06]

Hello sir, I'm using this to print on ATPOS thermal printer. The problem is it's not printing the whole data. I'm stuck here for a long time. Please help me. Below is my print function, please let me know where I'm going wrong.

testPrint(address , details , products:any = []) {

let CMD = data;
this.buff.clear();

this.buff.write(CMD.TEXT_FORMAT.TXT_ALIGN_CT);

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

    xyz.unsubscribe();

    let mno=this.alertCtrl.create({
      title:"ERROR "+err,
      buttons:['Dismiss']
    });
    mno.present();
  });

The project works for bluetooth. Since I am assuming you are connecting directly to a thermal printer, I don't think my code works.
