贾斯珀报告。如何使用指定的打印机驱动程序打印到文件？ [英] Jasper Report. How to print to a file using a specified printer driver?

问题描述

在控制面板中，我的打印机端口配置为文件：。
例如，我可以使用 PrintServiceAttributeSet 选择打印机，但打印时无法设置输出文件名。我不使用 JRXlsExporter 或 JRPdfExporter 或类似的东西，只需 JRPrintServiceExporter 。

In Control Panel my printer's port was configured to "FILE:". For example, I can select a printer using PrintServiceAttributeSet, but there is no way to set an output filename when printing. I don't use JRXlsExporter or JRPdfExporter or something like that, just JRPrintServiceExporter.

  PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet();
  printServiceAttributeSet.add(new PrinterName("Xerox DocuPrint 100 EPS PS3", null));
  //...
  exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, Boolean.FALSE);
  exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, Boolean.FALSE);
  //...
  exporter.exportReport();

驱动程序在PostScript中输出文件，但始终显示输出文件名窗口。如果我手动在窗口中设置文件名，则打印机会成功打印到文件。

The driver outputs files in PostScript, but a window "Output file name" appears all the time. If I set a filename in the window manually, then printer prints to a file successfully.

知道如何以编程方式设置文件名吗？

Any idea how to set a filename programmatically?

推荐答案

javax.print.attribute.standard »目的地有帮助。

解决方案：

  //...
  import javax.print.attribute.standard.Destination;
  //...

  JRExporter exporter = new JRPrintServiceExporter();          

  //--- Set print properties
  PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet();
  printRequestAttributeSet.add(MediaSizeName.ISO_A4);   

  //----------------------------------------------------     
  printRequestAttributeSet.add(new Destination(new java.net.URI("file:d:/output/report.ps")));
  //----------------------------------------------------     

  PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet();
  printServiceAttributeSet.add(new PrinterName("Xerox DocuPrint 100 EPS PS3", null)); 

  //--- Set print parameters      
  exporter.setParameter(JRExporterParameter.JASPER_PRINT, print);
  exporter.setParameter(JRPrintServiceExporterParameter.PRINT_REQUEST_ATTRIBUTE_SET, printRequestAttributeSet);      
  exporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE_ATTRIBUTE_SET, printServiceAttributeSet);      
  exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, Boolean.FALSE);
  exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, Boolean.FALSE);      

  //--- Print the document
  try{
      exporter.exportReport();
  }
  catch(JRException e){
      e.printStackTrace();
  }
