我有2台Epson TM-T81热敏打印机，1个USB，1个以太网端口。到目前为止，我每次只使用一台打印机。
我已经构建了一个c#代码，它可以打印到特定的打印机。现在我想有2台打印机与我的程序相关联。为此，我发现我需要调整我所在位置的configuration.xml：
C： \ProgramData\Microsoft\服务点\配置\配置.xml
我现在需要做什么改变来配置USB打印机。但我的以太网打印机将直接连接到我的无线路由器，该路由器已经安装，但没有更新configuration.xml。
这是我的c#代码
<code>
try
{
//Create PosExplorer
PosExplorer posExplorer = new PosExplorer();
DeviceInfo deviceInfo = null;
String strLogicalName="EpsonSale";
try
{
deviceInfo = posExplorer.GetDevice(DeviceType.PosPrinter, strLogicalName);
m_Printer = (PosPrinter)posExplorer.CreateInstance(deviceInfo);
}
catch (Exception)
{
//ChangeButtonStatus();
return;
}
//Register OutputCompleteEventHandler.
AddOutputComplete(m_Printer);
//Open the device
m_Printer.Open();
try
{
//Get the exclusive control right for the opened device.
//Then the device is disable from other application.
m_Printer.Claim(1000);
Console.WriteLine("Printer claimed");
}
catch (Exception e)
{
Console.WriteLine("Printer Not claimed");
}
//Enable the device.
m_Printer.DeviceEnabled = true;
//<<<step3>>>--Start
//Output by the high quality mode
m_Printer.RecLetterQuality = true;
}
catch(Exception){ Console.WriteLine("Printer Initialization failed.");}
包含服务对象的配置.xml文件：

这台打印机被正确地声明为USB打印机，但我如何为我的TCP/IP端口打印机添加服务对象？我在某个地方读到可以直接向该文件添加serviceObject，但我的属性是什么？此外，我使用的是TCP/IP端口，而不是"ESDPRT10xx"端口。我甚至尝试了Sean Liming的一个程序-SOMgr.exe来创建服务对象，但没有发现它有用。我无法使用posExplorer.GetDevice() 定位我的Epson打印机
此外，如果我在这篇文章的代码格式上有任何错误，我也很抱歉。
我不确定这是否会对您有所帮助。就我的情况而言，我使用JavaPOS而不是C#，并且我设法用以太网I/F卡打印到我的Epson TMU220。看看下面的xml配置文件。

我认为有一些值需要更改才能使其工作，例如：prop name="PortName"更改为"打印机IP地址"，而不是"ESDPRT001"。工作愉快！
