尝试使用Java打印PDF文件时遇到问题。这是我的代码:
PdfReader readFtp = new PdfReader(); // This class is used for reading a PDF file
PDDocument document = readFtp.readFTPFile(documentID);
printRequestAttributeSet.add(new PageRanges(1, 10));
job.setPageable(document);
job.print(printRequestAttributeSet); // calling for print
document.close()
我使用 document.silentPrint(job);
和 job.print(printRequestAttributeSet);
- 它运行正常。如果我使用 document.silentPrint(job);
- 我无法设置 PrintRequestAttributeSet
。
有谁能告诉我如何设置 PrintRequestAttributeSet ?

我的打印机不支持原生PDF打印。
我使用开源库Apache PDFBox https://pdfbox.apache.org来打印PDF。打印本身仍然由Java的PrinterJob处理。
import java.awt.print.PrinterJob;
import java.io.File;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.printing.PDFPageable;
public class PrintingExample {
public static void main(String args[]) throws Exception {
PDDocument document = PDDocument.load(new File("C:/temp/example.pdf"));
PrintService myPrintService = findPrintService("My Windows printer Name");
PrinterJob job = PrinterJob.getPrinterJob();
job.setPageable(new PDFPageable(document));
job.setPrintService(myPrintService);
job.print();
}
private static PrintService findPrintService(String printerName) {
PrintService[] printServices = PrintServiceLookup.lookupPrintServices(null, null);
for (PrintService printService : printServices) {
if (printService.getName().trim().equals(printerName)) {
return printService;
}
}
return null;
}
}

这对我来说可以用简单的JRE打印PDF:
public static void main(String[] args) throws PrintException, IOException {
DocFlavor flavor = DocFlavor.SERVICE_FORMATTED.PAGEABLE;
PrintRequestAttributeSet patts = new HashPrintRequestAttributeSet();
patts.add(Sides.DUPLEX);
PrintService[] ps = PrintServiceLookup.lookupPrintServices(flavor, patts);
if (ps.length == 0) {
throw new IllegalStateException("No Printer found");
}
System.out.println("Available printers: " + Arrays.asList(ps));
PrintService myService = null;
for (PrintService printService : ps) {
if (printService.getName().equals("Your printer name")) {
myService = printService;
break;
}
}
if (myService == null) {
throw new IllegalStateException("Printer not found");
}
FileInputStream fis = new FileInputStream("C:/Users/John Doe/Desktop/SamplePDF.pdf");
Doc pdfDoc = new SimpleDoc(fis, DocFlavor.INPUT_STREAM.AUTOSENSE, null);
DocPrintJob printJob = myService.createPrintJob();
printJob.print(pdfDoc, new HashPrintRequestAttributeSet());
fis.close();
}

以下内容适用于我使用打印对话框打印多个PDF文档:
public void printPDF()
{
PrinterJob printerJob = PrinterJob.getPrinterJob();
PrintService printService;
if(printerJob.printDialog())
{
printService = printerJob.getPrintService();
}
DocFlavor docType = DocFlavor.INPUT_STREAM.AUTOSENSE;
for (//fetch documents to be printed)
{
DocPrintJob printJob = printService.createPrintJob();
final byte[] byteStream = // fetch content in byte array;
Doc documentToBePrinted = new SimpleDoc(new ByteArrayInputStream(byteStream), docType, null);
printJob.print(documentToBePrinted, null);
}
}

试试这段代码:
FileInputStream fis = new FileInputStream(“C:/mypdf.pdf”);
Doc pdfDoc = new SimpleDoc(fis, null, null);
DocPrintJob printJob = printService.createPrintJob();
printJob.print(pdfDoc, new HashPrintRequestAttributeSet());
fis.close();

import java.awt.print.PrinterJob;
import java.io.File;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.printing.PDFPageable;
public class Main {
public static void main(String[] args) throws Exception {
String filename = "Path for PDF File";
PDDocument document = PDDocument.load(new File (filename));
//takes standard printer defined by OS
PrintService myPrintService = PrintServiceLookup.lookupDefaultPrintService();
myPrintService = findPrintService("Your Printer Name");
PrinterJob job = PrinterJob.getPrinterJob();
job.setPageable(new PDFPageable(document));
job.setPrintService(myPrintService);
job.print();
}
private static PrintService findPrintService(String printerName) {
PrintService[] printServices = PrintServiceLookup.lookupPrintServices(null, null);
for (PrintService printService : printServices) {
if (printService.getName().trim().equals(printerName)) {
return printService;
}
}
return null;
}
使用 Apache PDFBox 2.0.4 版。 如果使用 Maven 项目,请在 XML 文件中包含以下内容。
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>pdfbox</artifactId>
<version>2.0.4</version>
</dependency>

不推荐使用PDDocument的可分页实现,而是使用PDPageable适配器类并尝试使用setPrintable而不是setPageable:
job.setPrintable(new PDPageable(document));
