Epson OPOS ADK for .NET drivers for Windows 7

由 耗尽温柔 提交于 2019-12-18 18:03:07
问题 Has anyone used Epson OPOS ADK for .NET for Windows 7. I tried to install Windows Vista drivers on Windows 7 since there are none available for Windows 7, but it did not work. Please share any suggestions or ideas that might have worked for you. I am using a TM-88IV receipt printer. 回答1: It might be easier to use a generic text printer driver. Some of those specific OPOS drivers hog up CPU resource (either they are buggy or badly written). By using a generic text printer driver, you can send

OPOS image capture with Symbol Digital Image Scanner

问题 Our application presently uses the Motorola/Symbol DS6707 Digital Image Scanner for both image capture and barcode scanning. We communicate with the scanner via the Moto SNAPI driver. Since this is specific to the Motorola/Symbol scanner, I am considering a rewrite using a more generic interface, such as OPOS. This is in a C/C++ application. We also have a Honeywell imaging scanner in house that we are testing with. This model (Xenon 1900) also an supports both imaging and the barcode

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 - My program in C# shows text in “Microsoft LineDisplay Simulator” instead of the real display

问题 Hello lovely community! I am using a HP 2x20 Integrated Display with HP RP 7800 Retail System and decided to play with it and write some small programs for it to learn coding. The sample tool provided with the SDK works perfectly. First I wrote a simple program using Microsoft.IO.Ports and simple functions like this: SerialPort COM3 = new SerialPort("COM3", 9600, Parity.None, 8); COM3.Open(); COM3.Write(Clear); // string Clear = "\x1B\x40" - hex value of a control character for the display

Checking Printer Messages using OPOS Drivers in Delphi

问题 I'm trying to open a Point of Sale (POS) printer using the OPOS Drivers in Delphi (BDS2006), but don't have a clue on how to check the printer status. How would I check for messages like Check Paper and Paper Jam from the printer? 回答1: I haven't used OPOS Drivers but I have done some work with POS Drivers for an Epson receipt printer connected to a cash drawer. What I discovered was that, if the printer is installed in Windows, you can then open a direct connection to it and make it do

The reason the printer is so slow is that it's using the graphical font functions of Windows.

Implement OPOS Device in C#

问题 For some interop with a legacy POS application, I was wondering if it was possible to implement a phony OPOS device in C#. 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 called COM objects which are configured by registry keys. All of which should be implementable in C#. 回答1: Yes it's certainly possible. You can develop an OPOS SO

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?

Where can I find a “ESC/POS” Epson Barcode Test Program?

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. All the Delphi snippets I have so far is not working. The printer I am using is an Epson TM-L60II I Have a full tests program written in Delphi 5 for the TMT88's but the source is abit big for here so here is the barcode bits Please note that as its snippets from the full object
