<p>I am struggling to get an Epson "ESC/POS" printer to print barcodes (Using Delphi) and want to test if the printer is not faulty. Do you know where I can find a program to print a barcode in "ESC/POS"? I suppose as a last resort an OPOS program will also be OK.</p>

<p>Also, a demo Delphi Program that works will also be fine. All the Delphi snippets I have so far is not working.</p>

<p>The printer I am using is an Epson TM-L60II</p>

Get the Microsoft POS For .Net 1.11, it's got an SDK that includes a sample application that performs all the basic operations on POS hardware. I'm using it all the time to test that cash drawers work ok for example.
There's also a source code included (in .Net), so you can see how they do it.
