Epson Java Pos ADK 异常：未初始化

发布于 2024-10-03 23:20:11 字数 1442 浏览 5 评论 0原文

现在我尝试编写一个使用 Epson Java Pos ADK 的 Java 应用程序。

我做了什么： -安装Java 1.6.0_22 -安装Java JDK -安装Eclipse -安装了 Epson Java Pos ADK 1.11.8

然后我使用 Com Port Tool 尝试了我的打印机，我向他发送了十六进制字符以查看是否一切正常。确实如此！

然后我开始开发我的应用程序。在jpos.xml 中，我使用了 Epson Java Pos ADK 包中的 SetupPOS 生成器。

我用几行代码从我的应用程序中进行了测试打印：

posPrinter = new POSPrinter();
posPrinter.open("##THE_NAME_I_SET_IN_JPOS_XML##");      
posPrinter.claim(0);
posPrinter.setDeviceEnabled(true);
posPrinter.printNormal(station, "xxxxxxxxxxxxxxxxxx\n");
posPrinter.cutPaper(0);
posPrinter.release();
posPrinter.setDeviceEnabled(false);
posPrinter.close();

但是这个应用程序的结果是：

jpos.JposException：不是已初始化。在 jp.co.epson.upos.pntr.CommonPrinterService.checkInitialized（未知来源）于 jp.co.epson.upos.pntr.CommonPrinterService.sendOutputData（未知来源）于 jp.co.epson.upos.pntr.CommonPrinterService.sendOutputData（未知来源）于 jp.co.epson.upos.pntr.CommonPrinterService.executeNormalPrint（未知来源）于 jp.co.epson.upos.pntr.CommonPrinterService.printNormal（未知来源）于 jpos.POSPrinter.printNormal（未知来源）于打印机。（Printer.java:146）位于 Main.main(Main.java:28)

我在两台不同的电脑（Vista 和 XP 32 位）上尝试了这个，使用相同的版本和工具，但它总是相同的。

我还尝试了 JavaPos 示例测试应用程序和 EpsonHealtCheckTool。这个工具也是一样的。

不知道还能尝试什么，大家都知道这个问题吗？

PS：我的打印机 Epson TM-U220A，串行连接似乎可以工作，因为当我尝试声明打印机并且另一个应用程序使用 COM 端口时，我的应用程序说该端口不可用。

谢谢。

Now I try to write a Java Application what uses the Epson Java Pos ADK.

What I did:
-Installed Java 1.6.0_22
-Installed Java JDK
-Installed Eclipse
-Installed the Epson Java Pos ADK 1.11.8

Then I tried my Printer using Com Port Tool, I send him Hexadecimal Chars to see if all works. It does!

Then I started developing my Application. In the jpos.xml I used the SetupPOS generator within the Epson Java Pos ADK Package.

I used a few lines to make a test print from my Application:

posPrinter = new POSPrinter();
posPrinter.open("##THE_NAME_I_SET_IN_JPOS_XML##");      
posPrinter.claim(0);
posPrinter.setDeviceEnabled(true);
posPrinter.printNormal(station, "xxxxxxxxxxxxxxxxxx\n");
posPrinter.cutPaper(0);
posPrinter.release();
posPrinter.setDeviceEnabled(false);
posPrinter.close();

But the result of this app is:

jpos.JposException: It is not
initialized. at

Printer.(Printer.java:146) at
Main.main(Main.java:28)

I tried this on two different PC's (Vista and XP 32bit), with the same Versions and Tools, but it's always the same.

I also tried the JavaPos Example Test App and the EpsonHealtCheckTool. It's also the same with this tools.

Don't know what else to try, does everyone knows the problem?

PS: My Printer Epson TM-U220A, the serial connection seems to work, because when I try to claim the Printer and another Application uses the COM Port, My App says that the Port is not available.

Thanks.
