问题 I have an Epson TM-T88VI printer and use the Microsoft.PointOfService.PosPrinter in C# for printing. Using the following function i get a strange output printed: public static void printerTestFunction2(string printerName) { PosExplorer explorer = new PosExplorer(); DeviceInfo di = explorer.GetDevice("PosPrinter", printerName); PosPrinter printer = (PosPrinter)explorer.CreateInstance(di); printer.Open(); printer.Claim(10000); printer.DeviceEnabled = true; printer.AsyncMode = false; string init

问题 I use PosExplorer.GetDevices method to look for printers available on network. However, the DeviceInfo object in the DeviceCollection returned by GetDevices() method does not include information on LogicalNames, HardwareId, HardwarePath. In my app, I need to discover available printers and create an instance of those printers. I am using epson t88iv printers. 回答1: Thanks Sean Liming for the reply (http://www.seanliming.com/) POS for .NET can only be used for devices connected locally to the

POS for .Net print formatting - can't use escape character (char)27

问题 I figured out how to print basic text to our POS printer, but I can't figure out how to get the escape characters to work (for bold, text alignment, etc). For now I'm just testing with the Microsoft PosPrinter Simulator. Here's what I'm trying _printer.PrintNormal(PrinterStation.Receipt, (char)27 + "|bC" + printText + (char)13 + (char)10); I'd expect that to print my printText in bold followed by a line break. When I take out (char)27 + "|bC" then it works fine. The documentation for the

OPOS PosExplorer.GetDevice() returns null when executed in Windows Service

The code snippet below makes use of OPOS .NET to open a POS printer for printing. It works fine when executed as part of a standalone application. When executed by a Windows Service the call to GetDevice(...) always returns null. explorer = new PosExplorer(); device_info = explorer.GetDevice(DeviceType.PosPrinter, PrinterName); printer = (PosPrinter)explorer.CreateInstance(device_info); printer.Open(); printer.Claim(1000); printer.DeviceEnabled = true; The printer happens to be an Epson TM-U220B. Is there a security issue that needs to be overcome before a service has access to POS devices?
