Hi,
Any update on this ?
This is the code snippet I am using to print the labels. Need your inputs promptly.
void Print()
{
Connection connection = null;
try
{
if (selectedPrinter != null)
{
connection = DependencyService.Get().GetBluetoothConnection(printerList[0].Address);
connection.Open();
ZebraPrinter printer = ZebraPrinterFactory.GetInstance(connection);
ZebraPrinterLinkOs linkOsPrinter = ZebraPrinterFactory.CreateLinkOsPrinter(printer);
linkOsPrinter.StoreImage("R:IMAGE.GRF", Picture, 350, 262);
PrinterStatus printerStatus = linkOsPrinter?.GetCurrentStatus() ?? printer.GetCurrentStatus();
string errorMessage = GetPrinterStatusErrorMessage(printerStatus);
if (errorMessage == null)
{
connection.Write(SendZplReceipt(printer.PrinterControlLanguage));
}
else
{
}
}
else
{
}
}
catch (Exception ex)
{
connection?.Close();
Print();
}
finally
{
connection?.Close();
}
}

Hello Ashish,
Are you sure the sleep mode is really off? It looks like the printer goes to the sleep mode and your app can't connect to it.
Have you tried to initiate a new connection after receiving the error? If printer is in the sleep mode,  it will automatically wake up when a connection is initiated.
