PDFBox：如何使用指定的打印机打印pdf？
我想使用PDFBox打印由iText创建的PDF文件 。 我已经使用PDDocument类及其方法print（）成功地尝试了这个。 您可以在此处找到文档： http ： //pdfbox.apache.org/apidocs/ 。
（我正在使用此代码:)
public static void printPDF(String fileName) throws IOException, PrinterException { PDDocument doc = PDDocument.load(fileName); doc.print(); } 方法print（）效果很好，但有一个问题：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。
有没有办法如何只设置一次打印机？
对于打印机选择，我可以使用此代码，例如：
public static PrintService choosePrinter() { PrinterJob printJob = PrinterJob.getPrinterJob(); if(printJob.printDialog()) { return printJob.getPrintService(); } else { return null; } }
提前致谢
解：
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); }
PDDocument还提供除无参数print()之外的其他打印方法：
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。
您可以通过首先选择打印机获得所需的内容，然后调用silentPrint并相应地初始化PrinterJob实例。
PDDocument doc = PDDocument.load(new FileInputStream(System.getProperty("java.io.tmpdir") + "\\pdf.pdf")); //read pdf file. String printerNameDesired = "VENDOR THERMAL PRINTER"; javax.print.PrintService[] service = PrinterJob.lookupPrintServices(); DocPrintJob docPrintJob = null; int count = service.length; for (int i = 0; i < count; i++) { if (service[i].getName().equalsIgnoreCase(printerNameDesired)) { docPrintJob = service[i].createPrintJob(); i = count; } } PrinterJob pjob = PrinterJob.getPrinterJob(); pjob.setPrintService(docPrintJob.getPrintService()); pjob.setJobName("job"); doc.silentPrint(pjob);
import java.awt.print.PrinterException; import java.io.IOException; import org.apache.pdfbox.pdmodel.PDDocument; public class Print { public static void main(String[] args) throws IOException, PrinterException { PDDocument pdf=PDDocument.load("d:\\filename.pdf"); pdf.print(); } }
使用上面的代码使用apache Pdfbox打印pdf
编辑：版本2.0.0
import java.awt.print.PrinterException; import java.awt.print.PrinterJob; import java.io.File; import java.io.IOException; import org.apache.pdfbox.pdmodel.PDDocument; import org.apache.pdfbox.printing.PDFPageable; public class JPrint { public static void main(String[] args) throws IOException, PrinterException { String filename; filename = "C:\\pdf.pdf"; try { PDDocument pdf = PDDocument.load(new File(filename)); PrinterJob job = PrinterJob.getPrinterJob(); job.setPageable(new PDFPageable(pdf)); job.print(); } catch (Exception e) { System.out.println(e); } } }
您可以在PrinterJob对象上使用setPrintService（）方法 。
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; }
这对我来说很好。 但是旧版本的pdfbox。 新版本不支持.load和.silentprint
public static void print(String nomImpresora, int cantVia) throws Exception { String aux; PrintService[] services = PrintServiceLookup.lookupPrintServices(null, null); int selectedService = -1; if (nomImpresora != null) { for (int i = 0; i < services.length; i++) { aux = services[i].getName(); Log.addLog(Log.tipoMensaje.ErrorGenerico, "El valor de aux: " + aux + "."); if (services[i].getName().toUpperCase().contains(nomImpresora.toUpperCase())) { /*If the service is named as what we are querying we select it */ selectedService = i; } } } if (selectedService == -1) { new Exception("Impresora no encontrada " + nomImpresora); } File fileToPrint = new File(rutaNombreArchivo); PDDocument load = PDDocument.load(fileToPrint.toString()); try { PrinterJob printJob = PrinterJob.getPrinterJob(); Log.addLog(Log.tipoMensaje.ErrorSQL, "selected service" + selectedService); printJob.setPrintService(services[selectedService]); printJob.setJobName(fileToPrint.getName()); final HashPrintRequestAttributeSet printRequestAttributes = new HashPrintRequestAttributeSet(); printJob.print(printRequestAttributes); for (int i = 1; i <= cantVia; i++) { load.silentPrint(printJob); } } catch (final PrinterException e) { e.printStackTrace(); } finally { if (load != null) { load.close(); } } }
