Rule to print from Outlook Web App

I suspect this cannot be done, but I have not been able to find it written in any of the documentation I've searched from Microsoft. Is it simply not possible to create a rule to print email from the Outlook Web App?

Every once in a while I find something that seems impossible, can be done, but there's a little twist you have to know in order to do it. Just checking in case this is one of those situations.

Thanks!
