Javascript to Print Document and Summarize Comments

I am trying to create a button that will print my document and also print a summary of comments on a second page.

I have created the Print Button using this code but it does not give me that summary of comments.

var pp = this.getPrintParams();
pp.interactive = pp.constants.interactionLevel.silent;
pp.printContent = pp.constants.printContents. docAndComments;
this.print(pp);

Is there any additional code that I can add to give me that second page of comments?

Any help would be greatly appreciated.
