I got some sample code from MSDN using Microsoft.PointOfService package.
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.PointOfService;
namespace POS
{
public class CashDrawerClass
{
CashDrawer myCashDrawer;
PosExplorer explorer;
public CashDrawerClass()
{
explorer = new PosExplorer(this);
DeviceInfo ObjDevicesInfo = explorer.GetDevice("CashDrawer");
myCashDrawer = explorer.CreateInstance(ObjDevicesInfo);
}
public void OpenCashDrawer()
{
myCashDrawer.Open();
myCashDrawer.Claim(1000);
myCashDrawer.DeviceEnabled = true;
myCashDrawer.OpenDrawer();
myCashDrawer.DeviceEnabled = false;
myCashDrawer.Release();
myCashDrawer.Close();
}
}
}
