c# - PrintNormal()问题 'It is not Initialized'

当前的C#POS.NET打印问题:
PrintNormal()引发异常='未初始化'
CheckHealth ='未初始化'
打印到爱普生TM-T88IV时出现“未初始化”异常

使用POS for .NET 1.12和Epson OPOS ADK for .NET(v1.11.9)服务对象
成功打开，声明和设置PosPrinter的DeviceEnabled-true

在此之后发出将任何内容发送到打印机
PrintNormal()导致引发“未初始化”异常。
Epson OPOS ADK随附的CheckHealth实用程序会导致完全相同的错误。使用PrintNormal(PrinterStation.Receipt时，异常(exception)是“未安装指定的工作站。”

打印机使用直接并行打印效果很好
打印机本身打印

我们如何不能在消息“未初始化”中抛出豁免？

void K8POSPrint()
{
    /// <summary>
    /// PosPrinter object
    /// </summary>
    PosPrinter m_Printer = null;
    try
    {
        //Use a Logical Device Name which has been set on the SetupPOS.
        string strLogicalName = "PosPrinter";
        try
        {
            //Create PosExplorer
            PosExplorer posExplorer = new PosExplorer();
            DeviceInfo deviceInfo = null;

            try
            {
                // Device Info is not null when the printer has the logical name
                deviceInfo = posExplorer.GetDevice(DeviceType.PosPrinter, strLogicalName);
                m_Printer = (PosPrinter)posExplorer.CreateInstance(deviceInfo);
            }
            catch (Exception ExDevice)
            {
            }

            //Open the device
            m_Printer.Open();
            //Get the exclusive control right for the opened device. Then the device is disable from other application.
            m_Printer.Claim(1000);
            //Enable the device.
            m_Printer.DeviceEnabled = true;
            //    ////CheckHealth.
            //m_Printer.CheckHealth(Microsoft.PointOfService.HealthCheckLevel.Interactive);
            //    //As using the PrintNormal method, send strings to a printer, and print it [\n] is the standard code for starting a new line.
            /// Current Issue Next Line thows an exception - 'It is not initialized'
            m_Printer.PrintNormal(PrinterStation.Receipt, "Hey Now OPOS for .NET\n");
            // the next line would throw the exception 'The specified station is not mounted.'
            // m_Printer.PrintNormal(PrinterStation.Slip,"Hey Now Slip OPOS.NET\n");
        }
        catch (PosControlException)
        {

        }
    }
    catch (Exception ex)
    {

    }
}

附加信息:
尝试在pos打印机上打印时安装的程序是:
1.已安装的APD4打印机驱动程序Epson TI88IV
APD_412EWM.exe
https://www.epsonexpert.com/ee/techRes/index.htm?ProductId=570
在控制面板打印机中进行此设置之后，我可以选择打印机的属性并成功将测试打印到打印机上。
2.安装了Microsoft POS.NET 1.12
POSfor.NET.msi
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=eaae202a-0fcc-406a-8fde-35713d7841ca
3.已安装的Epson OPOS ADK v2.67

ADK267ER4.exe

https://www.epsonexpert.com/ee/appDev/appDevOPOS.htm
4.已安装适用于.NET 1.11.8的EPSON OPOS ADK
OPOSN 1 11 18.exe
https://www.epsonexpert.com/ee/appDev/appDevOPOS.htm
5.已安装的OPOS通用控件对象1.13.001

OPOS_CCOs_1.13.001.msi

http://monroecs.com/oposccos_current.htm
6. SetupPOS-添加的设备和逻辑名称
7.检查健康状况仍会引发错误
未初始化
OPOS_E_ILLEGAL 10007(0x00002717)

最佳答案

问题可能不是软件，而是硬件。我看到了一个类似的问题(在http://social.msdn.microsoft.com/Forums/vstudio/en-US/446fd4cc-db6b-4822-b3c8-7d9a98bf7eb4/it-is-not-initialized-when-trying-to-printnormal?forum=posfordotnet处)，其中开发人员使用的是不平行的延长电缆。一旦他将并行电缆直接连接到打印机(没有扩展电缆)，他的软件便开始工作。这是在他调用爱普生并订购一台更新的打印机之后，因为他们告诉他他的原始打印机与.NET不兼容，所以这也可能是您的问题。
