Hi Eric,
I have developed an ActiveX control for Viewing only of html files that allows for scalling and built-in print preview. Browse mode to print preview mode can be toggled back and forth. The print preview mode allows for scalling.
We developed it for one of our commercial products.
You can download the product (demo version) and take a look at the features of the viewer component.
If could help you then just email me at
