Get it on GitHub!
Up until recently we have always shared our printing sample code on the Zebra Support / Knowledge Management site. Due to popular demand, we have been migrating most of our samples to Github. In fact, you can find samples and source code for many Zebra products there. The printing samples are under the name LinkOS-OS-Samples. Each individual sample is on it's own branch.
Note: We will be shutting down the Knowledge Management site in the next month. We are working to update links, please keep in mind this is a content migration and be patient with us.
While we were going through our samples we found a few old code snippets. Here is one of them that some of you might still find useful:

This application demonstrates how to send ZPL commands to a network ZPL printer. It uses TcpClient to accomplish the communication. It was written in Visual Studio 2008 in C# and tested successfully on a Windows XP machine with Service Pack 3 .
Sample Code
Dim ipAddress As String = "10.3.14.59"
Dim port As Integer = 9100
Dim ZPLString As String = _
"^XA" & _
"^FO50,50" & _
"^A0N,50,50" & _
"^FDHello, World!^FS" & _
"^XZ"
Try
'Open Connection
Dim client As New System.Net.Sockets.TcpClient
client.Connect(ipAddress, port)
'Write ZPL String to Connection
Dim writer As New System.IO.StreamWriter(client.GetStream())
writer.Write(ZPLString)
writer.Flush()
'Close Connection
writer.Close()
client.Close()
Catch ex As Exception
'Catch Exception Here

Hi Everyone, For your reference, the Samples are branched from the main projects. Find them here:
