Reporting Service - print button shown on IE not shown on Firefox

Hi, I have my web application on which I use the ReportViewer to call a Server Report. I fill the report viewer and I see the report correctly on the IE 7, however on the Firefox the Print button does not appear, only the refresh. On the .Net the printButton is set to visible, just on Firefox does not appear...any one had this issue?Thanks a lot for helping!

Our friends at microsoft have decided to make the print function an ActiveX control, supported only by IE
