java-Linux上的自定义TG2480H USB
作者：互联网
我有JavaPOS和XML文件的示例代码,但是当我运行代码时,在printer.claim(1)上遇到了异常,我在此link上使用了示例的默认xml(pos.xml)文件
我已经将必需的本机驱动程序安装到/usr/java / packages / lib /中,因此本机驱动程序应该没有问题.
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);
}
}

解决方法:
根据dmesg日志,您的设备是TG2480(不是TG2480H),根据技术支持的电子邮件,该设备不支持JavaPOS.
