Linux 上的自定义 TG2480H USB

Question

我有 JavaPOS 和 XML 文件的示例代码，但是当我运行代码时，我在 printer.claim(1) 上遇到异常，我使用默认 xml (pos.xml) 这个例子的文件 link

我已经在/usr/java/packages/lib/中安装了必要的原生驱动，所以原生驱动应该没有问题。

代码：

import jpos.JposException;
import jpos.POSPrinter;
import jpos.POSPrinterConst;
import jpos.events.StatusUpdateEvent;
import jpos.events.StatusUpdateListener;
import jpos.util.JposPropertiesConst;
import java.util.StringTokenizer;

public class Printer {

    public static void main(String[] args) {

        System.setProperty(JposPropertiesConst.JPOS_POPULATOR_FILE_PROP_NAME, "jpos.xml");
        POSPrinter printer = new POSPrinter();

        // constants
        String ESC = ((char) 0x1b) + "";
        String LF = ((char) 0x0a) + "";

        try {
            //Open Printer
            printer.open("CUSTOM TG2480H POS Printer USB Linux");
            printer.claim(1);
            printer.setDeviceEnabled(true);

            //Print a Text String
            printer.printNormal(POSPrinterConst.PTR_S_RECEIPT, "Print Test");

            //Close Printer
            printer.setDeviceEnabled(false);
            printer.release();

            printer.close();

        } catch (JposException e) {
            // display any errors that come up
            e.printStackTrace();
        } finally {
            // close the printer object
            try {
                printer.close();
            } catch (Exception e) {
            }
        }

        System.exit(0);
    }
}

Answer 1

根据dmesg日志，您的设备是TG2480（不是TG2480H），根据技术支持的邮件不支持JavaPOS。
