I've seen tons of articles on email development, responsive deisn, here on Litmus and other sites like Campaign Monitor, Email on Acid and so on.

I've not seen a single write up on how the various email clients print emails.

I've noticed that Outlook often adds margins when going into the print view. Even a 500px email fill the page and outlook often stacks left aligned tables instead of displaying them side by side.

This happens in email that render perfectly well in the outlook viewing pane.

What's your experience of coding emails that will be printed out?
