Network printer - error when calling close

[JaydeeSale]

this.device.on("close", () => {
this.connected = false;

           if (this.retrying && (retries === 0 || this.retries < retries)) {
            this.retries++;
            setTimeout(() => {
                this.device.connect(this.options.port, this.options.address);
            }, 5000);
        }
        else { //this line will always hit and throw exception on close.
            this.retrying = false;
            throw new Error(`Cannot connect to ${this.options.address}:${this.options.port}`);
        }
    });

when calling close on the printer object the network adapter throws the exception, causing the awaiter to fail, trying to catch the exception has proven tough, causing node to crash. simple fix is to return upon retrying === false, and only throw the exception when it is in a retrying state
