How to trigger print in new window which is opened using RegisterClientScriptBlock in CS file

Question

This is my code to open it in new window, which works fine .

 ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "ViewDocument", "window.open('PdfViewer.aspx?fileName=" + displayFName + "  '  ,'_newtab');", true);

This above method opens and triggers print POP up window in IE, but not in Chrome. Should I be adding anything more to work in chrome? Please help me out here. Thanks.
