要在Java程序中调用GK888t打印机,你需要使用第三方库来实现。下面是一个简单的示例,演示如何使用Zebra打印机库打印标签:
1. 下载Zebra打印机Java库,可以在官方网站或者 Maven 上下载。如果你使用 Maven,可以在 `pom.xml` 文件中添加以下依赖:
```xml
<dependency>
<groupId>com.zebra</groupId>
<artifactId>zebra-sdk</artifactId>
<version>2.16.1</version>
</dependency>
```
2. 初始化打印机连接。你可以通过以下代码来连接打印机:
```java
import com.zebra.sdk.comm.Connection;
import com.zebra.sdk.comm.ConnectionException;
import com.zebra.sdk.comm.TcpConnection;
import com.zebra.sdk.printer.PrinterLanguage;
import com.zebra.sdk.printer.ZebraPrinter;
import com.zebra.sdk.printer.ZebraPrinterFactory;
import com.zebra.sdk.printer.ZebraPrinterLanguageUnknownException;
try {
Connection connection = new TcpConnection("192.168.1.100", TcpConnection.DEFAULT_ZPL_TCP_PORT);
connection.open();
ZebraPrinter printer = ZebraPrinterFactory.getInstance(connection);
PrinterLanguage pl = printer.getPrinterControlLanguage();
System.out.println("Printer language: " + pl);
connection.close();
} catch (ConnectionException | ZebraPrinterLanguageUnknownException e) {
e.printStackTrace();
}
```
3. 打印标签。你可以使用以下代码来打印标签:
```java
import com.zebra.sdk.graphics.ZebraImageI;
import com.zebra.sdk.printer.PrinterLanguage;
import com.zebra.sdk.printer.ZebraPrinter;
import com.zebra.sdk.printer.ZebraPrinterFactory;
import com.zebra.sdk.printer.ZebraPrinterLanguageUnknownException;
import com.zebra.sdk.printer.ZebraPrinterLinkOs;
try {
Connection connection = new TcpConnection("192.168.1.100", TcpConnection.DEFAULT_ZPL_TCP_PORT);
connection.open();
ZebraPrinter printer = ZebraPrinterFactory.getInstance(connection);
PrinterLanguage pl = printer.getPrinterControlLanguage();
System.out.println("Printer language: " + pl);
if (printer instanceof ZebraPrinterLinkOs) {
ZebraPrinterLinkOs linkOsPrinter = (ZebraPrinterLinkOs) printer;
ZebraImageI image = ZebraImageFactory.getImage("path/to/image.png");
linkOsPrinter.storeImage("MYIMAGE.GRF", image, image.getWidth(), image.getHeight());
linkOsPrinter.printStoredImage("MYIMAGE.GRF");
}
connection.close();
} catch (ConnectionException | ZebraPrinterLanguageUnknownException e) {
e.printStackTrace();
}
```
在上面的代码示例中,我们使用 `ZebraPrinterLinkOs` 接口来打印图片。如果你需要打印其他类型的内容,例如文本或条形码,可以使用 `ZebraPrinter` 接口提供的其他方法来实现。
