与 Epson FP-81 II（财务打印机）的通信错误

Question

当我下载驱动程序时，它们会分配后端代码。执行时，方法claim() return error 106.

// Console.WriteLine("Initializing PosExplorer ");
posExplorer = new PosExplorer();

// Console.WriteLine("Taking FiscalPrinter device ");
DeviceInfo fp = posExplorer.GetDevice("FiscalPrinter", "FiscalPrinter1");

// Console.WriteLine("Creating instance of FiscalPrinter device ");
posCommonFP = (PosCommon)posExplorer.CreateInstance(fp);
posCommonFP.StatusUpdateEvent += new StatusUpdateEventHandler(co_OnStatusUpdateEvent);

// Console.WriteLine("Initializing FiscalPrinter ");
FiscalPrinter fiscalprinter = (FiscalPrinter) posCommonFP;

Console.WriteLine("Performing Open() method ");
fiscalprinter.Open();

Console.WriteLine("Performing Claim() method ");
fiscalprinter.Claim(1000); // Exception

消息错误：

ErrorCode: Illegal
ErrorCodeExtended: 10002
Message: Stub message. LockPort Error. IORet = 4

Answer 1

请检查Epson.opos.tm.setpos.exe/SetupPOS.exe等设置的端口名是否正确

ErrorCodeExtended: 10002 将在下方。
在 "C:\Program Files (x86)\OPOS\Epson2\Include\epson.h".

中有描述

const LONG EPSNERREXT = 10000; // EPSON specific error base
const LONG OPOS_EX_BADPORT = 2 + EPSNERREXT; // invalid Port

在"C:\Program Files\epson\OPOS for.NET\Documentation\OPOS Error Code.pdf"

中有描述

Error Code  Extended Error Code
Illegal     EX_BADPORT
"The port name is illegal."

消息：存根 message.LockPort Error.IORet = 4 可能是 EPSON 内部的。

Answer 2

是否需要将型号打印机 FP-81 II 的端口更改为 9100。
