Hi,
We are trying to retrive printer current status inside a timer in iOS but sometimes we are receiving ErrorCode=7 .
 
We have done following:
 
1) First connecting the printer as shown in below sample code and it was successful.
 
                                   id connection; //It's a global variable
                connection = nil;
                connection = [[MfiBtPrinterConnection alloc] initWithSerialNumber:printerSerialNumber];
                [((MfiBtPrinterConnection*)connection) setTimeToWaitAfterWriteInMilliseconds:60];
                NSError *error = nil;
                BOOL didOpen = [connection open];
                if (didOpen) {
                    zebraPrinter = [ZebraPrinterFactory getInstance:connection error:&error];
                    if(error != nil) {
                        return;
                    }
                }
 
2) Then inside a timer, we are checking printer status as shown in below code sample:
 
                 id zebraPrinter;  //It's a global variable
        zebraPrinter = [ZebraPrinterFactory getInstance:connection error:&error];
        if(connection.isConnected)
        {
            PrinterStatus *status = [zebraPrinter getCurrentStatus:&error];
            if (error) {
                //Here SOMETIMES we are getting ErrorCode=7
                Error Domain=ZSDK_API_ERROR_DOMAIN Code=7 "Malformed status response - unable to      determine printer status" UserInfo={NSLocalizedDescription=Malformed status response - unable to determine printer status}
            }
        }
 
Please note:
 
- We are using latest zebra sdk (V1.5.1049)
- Printer Model: ZEBRA iMZ320
- iOS version 11.2.1
- We are NOT getting this error very frequently. But the error is there.
 
We have spend lots of time to find the exact reason (also sequence to re-prouce) of this error. But unable to find any proper solution.
Could you please let us know is there anything we are missing?
 
In advance thanks,
Molay
