Can you give us the code which you're using? Because its a bit hard to find out what it could be.

You have to open the connection before print and disconnect after. Here i attach an example.

  object = {
    type: 'tcp;
    title: 'Printer;
    ip: '192.168.1.211'; //ur IP
    port: 9100;
    id: 'printer;
 }
  printController;
  async printThermal(object) {
    let data =       {
      type: object.type,
      address: object.ip,
      mmFeedPaper: 700,
      dotsFeedPaper: 100,
      port: 9100,
      id: object.id, // Use an unique identifier for each printer i. e. address:port or name
      text:
        '[L]\n' +
        "[C]<u><font size='big'>ORDER N°045</font></u>\n" +
        '[L]\n' +
        '[C]================================\n' +
        '[L]\n'
        + '<0A0A0A0A0A1B>i<0D0A>'
    }
    this.printController = await ThermalPrinter.printFormattedTextAndCut(
      data,
      () => {
        console.log('Successfully printed!');
        this.discconectPrinter(object)
      },
      (error) => {
        console.error('Printing error', error.error);
      }
    );
  }

    discconectPrinter(object) {
    console.log("Desconectando impresora" + object.id);
    this.printController  = ThermalPrinter.disconnectPrinter(
      {
        type: object.type,
        address: object.ip,
        port: 9100,
        id: object.id, // Use an unique identifier for each printer i. e. address:port or name
      } as PrinterToUse,
      () => {
        console.log('Successfully disconnected!');
      },
      (error) => {
        console.error('Disconnecting error', error);
      }
    );
  }

If u dont disconnect printer after printing other devices cannot connect, hope it Helps. U can message me if u need it.
