如何在Java中打印PDF文件而不进行打印预览

Question

I generated a PDF file using JasperReports successfully; the creation of my PDF file is through a button trigger. After generating the file, I would like to print that PDF file in the printer without the PDF preview (Opening the PDF File then clicking the print button). My goal is when the user clicks the button that generates the PDF, it also will print that PDF in the default printer of that computer. BTW, I'm using Windows for this project and Java JRE7.

Check this blog http://blog.idrsolutions.com/2010/01/printing-pdf-files-from-java/ ; might helpful for you.

Also you could look for PDFRenderer Java API, might help.

Edit : How to set print attribute - Ref : http://docs.oracle.com/javase/7/docs/technotes/guides/jps/spec/attributes.fm4.html

PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
aset.add(new Copies(5)); 
aset.add(MediaSize.ISO_A4); 
aset.add(Sides.DUPLEX); 

Pass this attribute to printJob.print(pdfDoc, new HashPrintRequestAttributeSet()) Also, you could try getting the supported attribute first and then use accordingly. Please read the above documentation, it is very rich in examples.

我使用JPedal成功完成了任务，现在可以使用代码将pdf文件直接以实际大小打印到打印机上

decodePdf.setPrintPageScalingMode(PrinterOptions.PAGE_SCALING_REDUCE_TO_PRINTER_MARGINS);
