PrintDialog NamedAction is done with JavaScript- not Adobe Named Action

I am using Aspose PDF to add a PrintDialog NamedAction as the OpenAction of a generated PDF like so:

var printAction = new NamedAction(PredefinedAction.PrintDialog);
PdfDoc.OpenAction = printAction;

However, the action of launching the print dialog is never fired when this PDF is opened in FireFox, because the action exists as JavaScript within the PDF file. Within the PDF I have found:

8 0 obj
<</Type/Catalog/Version/1.7/Pages 1 0 R/Outlines 2 0R/OpenAction<</S/JavaScript/JS(this.print(true);\015)>>/Metadata 4 0 R>>

In FireFox’s pdf.js viewer, JavaScript is blocked from running and so the print dialog is never launched (the same is probably true for other pdf readers).

Is it possible to replace how the PrintDialog NamedAction is handled behind the scenes, from JavaScript to a real Adobe named action?

For example:
56 0 obj

This would allow the action to actually be fired in affected pdf viewers.

Hi There,

Thanks for contacting support.

You can add JavaScript against page action. In order to accomplish this requirement, PageActionCollection is implemented. This class has properties:
  • public PdfAction OnOpen
  • public PdfAction OnClose
You may use following code snippet to accomplish your task.


JavascriptAction javascript = new JavascriptAction(“this.print({bUI:true,bSilent:false,bShrinkToFit:true});”);
pdf.OpenAction = javascript;

Moreover, I have tested the scenario with above code and have observed print Dialogue does not appear in Firefox browser. For the sake of correction, I have logged a ticket PDFNET-42481 in our issue tracking system. We will further look into the details of this issue and will keep you updated regarding the resolution of this issue within this forum thread. Please be patient and spare us a little time.
