使用 Apache PDFBox 打印 PDF

Apache PDFBox 是一个开源的 Java 库，支持 PDF 文档的创建、操作和打印。

确保在项目中添加 PDFBox 依赖：

<dependency>
    <groupId>org.apache.pdfbox</groupId>
    <artifactId>pdfbox</artifactId>
    <version>2.0.27</version>
</dependency>

打印 PDF 的代码示例：

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.printing.PDFPageable;

import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import java.awt.print.PrinterJob;
import java.io.File;

public class PDFPrinter {
    public static void printPDF(String filePath) throws Exception {
        PDDocument document = PDDocument.load(new File(filePath));
        PrinterJob job = PrinterJob.getPrinterJob();

        PrintService[] services = PrintServiceLookup.lookupPrintServices(null, null);
        if (services.length > 0) {
            job.setPrintService(services[0]);
            job.setPageable(new PDFPageable(document));
            job.print();
        }
        document.close();
    }
}

使用 iText 打印 PDF

iText 是另一个流行的 Java PDF 库，支持 PDF 打印功能。

添加 iText 依赖：

<dependency>
    <groupId>com.itextpdf</groupId>
    <artifactId>itextpdf</artifactId>
    <version>5.5.13</version>
</dependency>

打印代码示例：

import com.itextpdf.text.Document;
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.PdfWriter;

import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import java.awt.print.PrinterJob;

public class PDFPrinter {
    public static void printPDF(String filePath) throws Exception {
        PdfReader reader = new PdfReader(filePath);
        PrinterJob job = PrinterJob.getPrinterJob();

        PrintService[] services = PrintServiceLookup.lookupPrintServices(null, null);
        if (services.length > 0) {
            job.setPrintService(services[0]);
            Document document = new Document();
            PdfWriter writer = PdfWriter.getInstance(document, job.getPrintService().createPrintJob());
            document.open();
            document.newPage();
            document.close();
            writer.close();
        }
        reader.close();
    }
}

使用 Java 原生打印 API

Java 提供了原生的打印 API，可以直接用于打印 PDF 文件。

代码示例：

import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.SimpleDoc;
import javax.print.attribute.HashPrintRequestAttributeSet;
import java.io.FileInputStream;

public class PDFPrinter {
    public static void printPDF(String filePath) throws Exception {
        FileInputStream fis = new FileInputStream(filePath);
        DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
        Doc doc = new SimpleDoc(fis, flavor, null);

        PrintService[] services = PrintServiceLookup.lookupPrintServices(flavor, null);
        if (services.length > 0) {
            DocPrintJob job = services[0].createPrintJob();
            job.print(doc, new HashPrintRequestAttributeSet());
        }
        fis.close();
    }
}

使用外部工具打印 PDF

可以通过命令行调用外部工具（如 Adobe Reader）打印 PDF。

代码示例：

如何java打印pdf

import java.io.IOException;

public class PDFPrinter {
    public static void printPDF(String filePath) throws IOException {
        String command = "cmd /c start acrord32 /p /h " + filePath;
        Runtime.getRuntime().exec(command);
    }
}
