在 Java 中使用 PrinterJob 打印 PDF 文件

我在尝试使用 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()

I use document.silentPrint(job); and job.print(printRequestAttributeSet);- 效果很好。如果我使用document.silentPrint(job);- 我无法设置PrintRequestAttributeSet.

谁能告诉我如何设置打印请求属性集?

我的打印机不支持本机 PDF 打印。

我使用了开源库 Apache PDFBoxhttps://pdfbox.apache.org https://pdfbox.apache.org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;
    }
}
