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. Also, a demo Delphi Program that works will also be fine.

Basically I would implement a phony keyboard that took web requests and passed on key presses to the legacy application. Does anyone know if this is possible or where to get documentation? I figured OPOS just call...
We currently have check printing fully implemented and in the field for a POS application. It runs on Windows, implemented in C# and uses POS for .Net. We are having an issue where cashiers are too eager and pull out the check a second or so before it is finished franking. If the check is pulled out during the printing process, we can...

We're trying implement a .NET Service Object that supports a COM interface to emulate a POSPrinter but still be compatible with the older technologies. We have our interface and class object in the following class.. using [...] namespace yRPOSPrinterDotNet { [Guid("2D570F11-4BD8-40e7-BF14-38772063AAF0")] [InterfaceType(ComIn...

Anyone have experience with OPOS? I can't get my app to recognize the LDNs for the devices running on a 64 bit machine. I've got down to the point where I know that the OleforRetail stuff is now under Wow6432Node in the Registry. I suspect the common controls can't find the LDN because of this. Is there any kind of workaround? Failing ...
I would like intercept print instruction from POS (Point-of-Sale) systems, capture the text content(as I need to use this) and send it to the printer. And would also like to use a program with OPOS standards, so that it will work with all kinds of POS system. I looked into MS POS .Net and and samples from MONORECS and still not clear on ...

According to the Monroe documentation, the SO initiates events by calling an event request method exposed by the Control Object. So, as far I understand, in my SO I should declare and initialize the Monroe CO and to fire an event I should call the...

When executed by a Windows Service the call to GetDevice(...) always returns null. explorer = new PosExplorer(); device_info = explorer.GetDevice(DeviceType.PosPrinter, PrinterName); printer ...
