One workaround might be to forward it to a special address (say the "server" Mac hosting a printer). If you use mail on mac os x (or any mail client you can script), create a mail rule that when it matches that special e-mail, it runs an AppleScript which prints the e-mail and/or attachment.
YES this can be done but is not easy, it would need a script as you said.
another way is to use soonr.com this enables printing, skype, searching plus a lot more. on your mac or PC here is a basic script i use over a network.
