c# – PrintNormal()问题’它没有初始化’

当前C#POS.NET打印问题：

Printnormal()抛出异常=’它未初始化’
CheckHealth =’它未初始化’
打印到Epson TM-T88IV时,“未初始化”例外

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

在此之后向打印机发送任何内容
Printnormal()导致抛出“未初始化”异常.
Epson OPOS ADK附带的CheckHealth Utility会产生完全相同的错误.使用Printnormal时(PrinterStation.Receipt例外是’未安装指定的工作站’.

打印机使用直接并行打印精细
打印机本身打印

我们怎么能不把这个豁免 – “它没有被初始化”？

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后,我可以选择打印机的属性&将测试成功打印到打印机.
2.安装Microsoft POS.NET 1.12
POSfor.NET.msi
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=eaae202a-0fcc-406a-8fde-35713d7841ca
3.安装Epson OPOS ADK v2.67

ADK267ER4.exe

https://www.epsonexpert.com/ee/appDev/appDevOPOS.htm
4.安装了EPSON OPOS ADK for .NET 1.11.8
OPOSN 1 11 18.exe
https://www.epsonexpert.com/ee/appDev/appDevOPOS.htm
5.安装的OPOS通用控制对象1.13.001

OPOS_CCOs_1.13.001.msi

http://monroecs.com/oposccos_current.htm
6. SetupPOS – 添加设备&逻辑名称
7.检查健康仍会引发错误
它没有初始化
OPOS_E_ILLEgal 10007(0x00002717)

解决方法

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),开发人员使用的是不平行的延长线.一旦他将并行电缆直接连接到打印机(没有延长电缆),他的软件就可以工作了.这是在他打电话给Epson并订购了一台更新的打印机之后,因为他们告诉他原来的打印机与.NET不兼容,所以这也可能是你的问题.
