Unknown Error return while checkPrinterStatus

[AlexThoh88]

Hi,

I had tried the sample provided and getting "Unknown Error" when the code pass through checkPrinterStatus. After my further study, the message return from read() is 'Unauthorized device detected'. Any advise?

Thank you.

Hi,
u got the same errors as you.
i guess i skiped the status check because i think there are some issues with it.
i just called browserPrint.print despite having "unkown error" and it's printing without issues.

Hi,
I had the same problem.
I resolved the 'Unauthorized device detected' by changing the uid. Because I found out that it's necessary the :9100 even in the uid, and they parse ":" from the json given by the function "getDefaultPrinter" (const uid = this.cleanUpString(deviceRaw[4]); )
What I did is modifying the function clenUpString from

  cleanUpString = (str: string): string => {
    const arr = str.split(':');
    const result = arr[1].trim();
    return result;
  };

to:

  cleanUpString = (str: string): string => {
    const arr = str.split(':');
    const result = arr.slice(1).join(":").trim();
    return result;
  };

I still get "Unknown Error" in the response, but at least I can print the labels as @issabm suggests.

I'm having the unknown error issue too, I'm seeing ~HQES get printed - not sure what that means. Any help would be appreciated! Printing on a ZD421 and using Browser Print v1.3.1.445
