以下是使用Java调用斑马GK888t打印机的ZPL指令的示例代码:
```java
import java.io.IOException;
import java.io.OutputStream;
import java.net.Socket;
public class ZplPrinter {
private final String ipAddress;
private final int portNumber;
public ZplPrinter(String ipAddress, int portNumber) {
this.ipAddress = ipAddress;
this.portNumber = portNumber;
}
public void printLabel(String zplCommand) throws IOException {
Socket printerSocket = null;
OutputStream outputStream = null;
try {
printerSocket = new Socket(ipAddress, portNumber);
outputStream = printerSocket.getOutputStream();
// Send the ZPL command to the printer
outputStream.write(zplCommand.getBytes());
outputStream.flush();
} finally {
if (outputStream != null) {
outputStream.close();
}
if (printerSocket != null) {
printerSocket.close();
}
}
}
}
```
使用该类,您可以创建一个ZplPrinter对象并使用printLabel方法将ZPL指令发送到打印机。例如,以下是如何使用该类打印一张标签的示例代码:
```java
public static void main(String[] args) throws IOException {
ZplPrinter printer = new ZplPrinter("192.168.1.100", 9100);
String zplCommand = "^XA" +
"^FO50,50" +
"^A0N,50,50" +
"^FDHello, World!^FS" +
"^XZ";
printer.printLabel(zplCommand);
}
```
在上面的代码中,我们创建了一个ZplPrinter对象,并将其IP地址设置为192.168.1.100,端口号设置为9100。然后,我们创建一个包含ZPL指令的字符串,并将其传递给printLabel方法来打印标签。
