VB App as a 'printer'

I need to simplify a HTML page to email to someone else.
I've knocked up an app whcih takes a file name as a command line parameter, processes it as required and saves it to a new file.

It would be better if I could integrate it with a webbrowser so using it is a simple as selecting an alternative printer.

Any ideas?

Thanks

Can someone explain what this means, please?

You can't use VB to produce a virtual printer driver. Maybe you could let your application automate IE instead and react to the proper event, or you could use a web browser control and create your own IE clone to which you add this feature.
