Print From ZPL String

Is there a way to send a ZPL string using .net linkOS sdk?  I know you can print from file, but in order to make it faster I would like to save my string in the Database or even in code and just send it.

Thanks,

Paul

Hi Paul, Yes definitely.
You can just use the connection.Write() to send a ZPL string to the printer.
TcpConnection Class
// from the TCPConnection Class on Zebra Techdocs:private void SendZplOverTcp(string theIpAddress) {  // Instantiate connection for ZPL TCP port at given address  Connection thePrinterConn = new TcpConnection(theIpAddress, TcpConnection.DEFAULT_ZPL_TCP_PORT);  try {  // Open the connection - physical connection is established here.  thePrinterConn.Open();  // This example prints "This is a ZPL test." near the top of the label.  string zplData = "^XA^FO20,20^A0N,25,25^FDThis is a ZPL test.^FS^XZ";  // Send the data to printer as a byte array.  thePrinterConn.Write(Encoding.UTF8.GetBytes(zplData));  } catch (ConnectionException e) {  // Handle communications error here.  Console.WriteLine(e.ToString());  } finally {  // Close the connection to release resources.  thePrinterConn.Close();  }  }
