ZPL

Purpose

This sample code demonstrates how to open up a raw socket connection to a network ZPL printer and send a label down for printing.  It was written in C# using Visual Studio 2008 Professional and tested successfully on a Windows XP Machine Service Pack 3.

Sample Code

// Printer IP Address and communication port

string ipAddress ="10.3.14.42";

int port = 9100;

 

// ZPL Command(s)

string ZPLString =

   "^XA" +

   "^FO50,50" +

   "^A0N50,50" +

   "^FDHello, World!^FS" +

   "^XZ";

 

try

{

   // Open connection

    System.Net.Sockets.TcpClient client =new System.Net.Sockets.TcpClient();

    client.Connect(ipAddress, port);

 

   // Write ZPL String to connection

    System.IO.StreamWriter writer =

new System.IO.StreamWriter(client.GetStream());

    writer.Write(ZPLString);

    writer.Flush();

 

   // Close Connection

    writer.Close();

    client.Close();

}

catch (Exception ex)

{

    // Catch Exception
