Same results in that I also get source code as a printout.
So far I've just searched the web.
I haven't tried uninstalling or repairing Internet Explorer,
especially since, when I've tried in the past with IE6 it has
proven itself resistant to uninstalling and I'm not sure how
to go about repairing it.
Given that I'm also having the problem with Help files (such as
in Excel), I'm not sure that's going to fix the problem.
I've also seen that this may be related to a possible virus, so,
I've installed and run AVG Anti-Virus software and come up with,
and cleaned out the "I-Worm/SoBigF" virus which was the only virus
detected.
I've also run the web based virus detection software at Trend Micro:
http://housecall.trendmicro.com/
It didn't find anything.
I've also searched Microsoft's Support site, but, didn't really find
anything useful.
I searched in the knowledgebase under:
Internet Explorer
printing problem
Internet Explorer
web page printing problem
Internet Explorer
printing html
The closest comparable solution I found was for IE 5 as I recall
and it suggested looking for a "Style" entry in the registry which
I did and didn't find.
That's about it.
