Currently Synapse uses IE 7/8 to print HTML documents because there is an ActiveX control to enable one to control the footer and header.
However, I have now discovered a Firefox add-on that does a similar thing, and so I can now support HTML printing from Firefox. Without the add-on, you would have to adjust the footer and headers each time you wanted to print.
The add-on is here http://downloads.mozdev.org/jsprintsetup/jsprintsetup-0.8.2f.xpi
And the documentation http://jsprintsetup.mozdev.org/index.html
I plan to offer users the ability to print from either FF or IE.
