如何使用原生JAVA打印PDF文件(或打开并打印)

PdfDocument pdfDoc = new PdfDocument(new PdfReader("path/to/your/pdf/file.pdf"));

PrintService[] printServices = PrintServiceLookup.lookupPrintServices(null, null);
for (PrintService printer : printServices) {
    System.out.println(printer.getName());
}

PrintService selectedPrinter = null;
for (PrintService printer : printServices) {
    if (printer.getName().equals("My Printer")) {
        selectedPrinter = printer;
        break;
    }
}

PrintJob printJob = selectedPrinter.createPrintJob();
pdfDoc.print(printJob);

printJob.print();

import com.itextpdf.text.pdf.PdfDocument;
import com.itextpdf.text.pdf.PdfReader;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.PrintJob;

public class PDFPrinter {
    public static void main(String[] args) {
        try {
            // 打开PDF文件
            PdfDocument pdfDoc = new PdfDocument(new PdfReader("path/to/your/pdf/file.pdf"));

            // 获取打印机列表
            PrintService[] printServices = PrintServiceLookup.lookupPrintServices(null, null);
            for (PrintService printer : printServices) {
                System.out.println(printer.getName());
            }

            // 选择打印机
            PrintService selectedPrinter = null;
            for (PrintService printer : printServices) {
                if (printer.getName().equals("My Printer")) {
                    selectedPrinter = printer;
                    break;
                }
            }

            // 创建打印任务
            PrintJob printJob = selectedPrinter.createPrintJob();
            pdfDoc.print(printJob);

            // 打印PDF文件
            printJob.print();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
