PrintNormal() Issue 'It is not Initialized'

Question

Current C# POS.NET Printing Issue:

PrintNormal() Throws Exception = 'It is not initialized'
CheckHealth = 'It is not initialized' 'It is not initialized' exception when Printing to Epson TM-T88IV

Using POS for .NET 1.12 and the Epson OPOS ADK for .NET (v1.11.9) service-objects Successfully able to Open, Claim and Set the DeviceEnabled-true for PosPrinter

Issue sending anything to the printer after this PrintNormal() results in a 'It is not initialized' exception being thrown. CheckHealth Utility that came with the Epson OPOS ADK results in exactly the same error. When using PrintNormal(PrinterStation.Receipt the exception is 'The specified station is not mounted."

printer prints fine using direct parallel printer itself prints

How can we not throw the exemption with the message - 'It is not initialized'?

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)
    {

    }
}

I think your try catch nesting is the problem, you don't get the real problem here. Try to remove some of the Try catch codes and leave only one. Then you'll see what the real problem is. – Alloy

Do you have a OPOS printer named PosPrinter set up? You can check in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\OLEforRetail\ServiceOPOS\PosPrinter` there should be a sub key named PosPrinter. Is the printer setup in Windows in Printers and Devices, if it is try removing? From what I recall if the printer is set up in Windows it will not always work in OPOS. – Hannelorehanner

Answer 1

The problem might not be software, but hardware. I saw a similar question (at http://social.msdn.microsoft.com/Forums/vstudio/en-US/446fd4cc-db6b-4822-b3c8-7d9a98bf7eb4/it-is-not-initialized-when-trying-to-printnormal?forum=posfordotnet), where the developer was using an extension cable which was not parallel. As soon as he connected the parallel cable directly to the printer (without the extension cable), his software worked. This was after he called Epson and ordered a newer printer, because they told him his original printer was not compatible with .NET, so that could also be your problem.

I had the same error "It is not initialized" on brand new Epson TM-T88VI. The printer came with IDN Card and default the ethernet card was partially blocked. You can use the ethernet card to connect to "Epson Net Config", but it did not work when you try to print by OPOS ADK for NET. The solution was to set switches on IDN Card as:

DS1	DS2	DS3	DS4	DS5	DS6	DS7
OFF	OFF	OFF	OFF	ON	ON	ON

Make sure Power OFF when you changing the switches.
