Right now, you can't determine if an e-note has a printer or scanner attached by looking at it or inspecting it. It would be cool if looking at an e-note showed its attachments (and perhaps how much is left in its attached e-print, if it has one.)
While this doesn't quite solve your problem, "look e-print on e-note" shows the e-print if there is one attached, as well as the number of papers remaining in it.
