一、前言

    今天做打印方面的东西，网上找了一个工具类，这里记录下

二、引入maven

    <dependency>
        <groupId>org.apache.pdfbox</groupId>
        <artifactId>pdfbox</artifactId>    
        <version>2.0.6</version>
    </dependency>

三、直接贴代码

    import org.apache.pdfbox.pdmodel.PDDocument;
    import org.apache.pdfbox.printing.PDFPrintable;
    import org.apache.pdfbox.printing.Scaling;
    import javax.print.*;
    import javax.print.attribute.HashPrintRequestAttributeSet;
    import javax.print.attribute.PrintRequestAttributeSet;
    import javax.print.attribute.standard.Copies;
    import javax.print.attribute.standard.MediaSize;
    import javax.print.attribute.standard.Sides;
    import java.awt.print.Book;
    import java.awt.print.PageFormat;
    import java.awt.print.Paper;
    import java.awt.print.PrinterJob;
    import java.io.*;

            // JPGPrint(file,printerName);
            PDFPrint(file,printerName);
        }
        // 传入文件和打印机名称
        public static void JPGPrint(File file,String printerName) throws PrintException {
