    # item = ::Item.joins(:projects).where(projects: {id: params[:order_id].to_i}).first
    # printer = ::Printer.where(supplier_id: current_user.supplier_id, default: true).first

    # # Preso l'ordine mi recupero l'item e ne stampo la quantità richiesta
    # ::PrintWorker.perform_async('192.168.0.1', 9100, "We all love DJ")
