PDFBox:如何使用指定的打印机打印 pdf? [英] PDFBox: How to print pdf with specified printer?

问题描述

我想用 PDFBox 打印 iText 创建的 PDF 文件.我已经使用 PDDocument 类及其方法 print() 成功地尝试了这一点.您可以在此处找到文档:http://pdfbox.apache.org/apidocs/.

I want to use PDFBox for printing PDF files created by iText. I have tried this successfully with PDDocument class and its method print(). You can find documentation here: http://pdfbox.apache.org/apidocs/.

(我正在使用此代码:)

(I am using this code:)

public static void printPDF(String fileName)
        throws IOException, PrinterException {
    PDDocument doc = PDDocument.load(fileName);
    doc.print();
}

print() 方法很好用，但是有一个问题:当我需要打印多个文件时，该方法要求我为每个文件选择打印机..

The method print() works great, but there is one problem: When I need to print multiple files, the method asks me to select printer for each one of documents..

有没有办法只设置一次打印机?

对于打印机选择，我可以使用以下代码，例如:

For printer selection I can use this code for example:

public static PrintService choosePrinter() {
    PrinterJob printJob = PrinterJob.getPrinterJob();
    if(printJob.printDialog()) {
        return printJob.getPrintService();          
    }
    else {
        return null;
    }
}

提前致谢

public static PrintService choosePrinter() {
    PrinterJob printJob = PrinterJob.getPrinterJob();
    if(printJob.printDialog()) {
        return printJob.getPrintService();          
    }
    else {
        return null;
    }
}

public static void printPDF(String fileName, PrintService printer)
        throws IOException, PrinterException {
    PrinterJob job = PrinterJob.getPrinterJob();
    job.setPrintService(printer);
    PDDocument doc = PDDocument.load(fileName);
    doc.silentPrint(job);
}

推荐答案

PDDocument 还提供了除无参数print()之外的其他打印方法:

PDDocument also offers other print methods than the parameterless print():

public void print(PrinterJob printJob) throws PrinterException;
public void silentPrint() throws PrinterException;
public void silentPrint(PrinterJob printJob) throws PrinterException;

silentPrint 方法不显示对话框.

您可以先选择一台打印机，然后调用 silentPrint 并相应地初始化 PrinterJob 实例，从而得到您想要的结果.

You may get what you want by first selecting a printer and then call silentPrint with PrinterJob instances initialized accordingly.
