flexreport横幅打印初步总结

1- 

flexreport基于alivepdf

可以打印较清晰的文字（包括控件上的文字和文本框中的文字...）。

关于横向打印功能，现阶段的结论是无法实现，因为受到printJob:FlexPrintJob的制约， 打印机宽，高，属性是只读的无法修改，printJob.start() 自后仍然无法修改。

AIR程序中flash.printing.PrintJob经过初步测试同样无法修改属性，官方api内容：“图像的打印方向。此属性是 PrintJobOrientation 类中的一个值。仅当调用 PrintJob.start() 方法后，此属性才是可用的。 ”，仍需要进一步测试。

现实使用方案： 1,手动修改flexreport的PaperFormat.A4R宽高参数，要求用户将打印机的默认设置改为纵向打印。2，使用javascript修改，具体实现方法不确定（注册表，安全限制等）。

测试中：_template.rotation=90; 结论：旋转后文字无法显示，使用字体样式后文字可以旋转，但只能对lable单体旋转时有效；

AIR2中加入了新的打印机选项，可以实现横幅打印等打印记设置

pj.selectPaperSize(PaperSize.A4); 

pj.orientation = PrintJobOrientation.LANDSCAPE; 

pj.copies = 1; 

pj.jobName = "Flash test print";

此文章提及了纵向打印修改设置内容，但测试发现是不可用的。

 

Flex Report

kemelyon  FlexReport 0_2rc1 (LGPL)

1. Layout  A4,A3,A4R (landscape)
2. Print Preview
3. Multipage Print

3 Issue Fixed

-  A4R print in source PaperFormat.as line 54

new PaperFormat([842, 595],“A4.Rotated”,[8.27,11.9],[210,297]);

-  Error: Error #2030: End of file was encountered  at flash.display::BitmapData/setPixels()

example code   refer to FlexReportDemo.mxml

  private function generateDocument():void
  {
   var source:ReportDP = new ReportDP();
   var report:PortfolioReport = new PortfolioReport();
   report.width = PaperFormat.A4R.width; // add this
   report.height = PaperFormat.A4R.height;// add this
   doc = new Document(report, source, PaperFormat.A4R);
   doc.pdfEnabled = false;
   printPreview.doc = doc;
  }
  private function initApplication():void
  {
  printPreview.pdfExportEnabled = false;
  printPreview.page.width = PaperFormat.A4.width; // add this
  printPreview.page.height = PaperFormat.A4.height; //add this
  generateDocument();
  }

- print blank page or grey rectangle in the upper right corner Issue.

if (printJob.start()) {
   setUpTemplate();
   Application.application.addChild(template);
   _template.height = printJob.pageHeight; // add this
   _template.width = printJob.pageWidth;   // add this
   _template.validateNow();
   _template.reset();

参考2：

If you need to switch the layout to Landscape try the following (I used A4R):

1. In org.doc.PaperFormat.as switch the sizes in the A4R declaration:

public static const A4R : PaperFormat = new PaperFormat([842, 595],”A4.Rotated”,[11.9, 8.27],[297, 210]);

(not sure why A4R is the same as A4…)

2. add A4R to the paperFormats Array:

public static var paperFormats:Array = new Array(A3,A4,A4R, A5,LETTER,LEGAL,TABLOID);

3. In Preview.mxml change the width and height:

4. In FlexReportDemo.mxml change the Document() parameters:

doc = new Document(report, source, PaperFormat.A4R);

5. in DemoReport.mxml switch the height and width parameters:

That should get you landscape quickly to test preview (unless I missed something…  ). The PDF print still needs work…
