I would look carefully at the overall design of the system. For instance, if the printer was placed at the top of the stack, it would be less likely to receive fluid ingress (we hope) ... but there again, how would the paper tray (or whatever) be accessed?
Also, have you considered using wireless technology to keep the "non-medical" items well away from the patient (and the patient zone)? Or, why include a printer at all? Just provide some sort (or many sorts of) memory device, and/or interface to the intranet ... and let the user worry about the printer.
Integrating equipment components into a well thought out system is always interesting, but without seeing the actual kit involved, it's a bit difficult to comment further.
But, as I tried to stress earlier, you will have your ducks in a row later on, when you get challenged by every clever Tom, Dick and Ali you encounter in the hospitals.
By the way, was I dreaming, or did I hear recently that legislation is on the way that will require a centralised protective earth point in every "patient environment" by the year 20?? (whenever)? Remember the famous "equipotential point", so beloved by DIN (I think it was)?
OK, another year (month), another standard. Necessary? I doubt it, but there won't be any choice whether to implement or not, of course. Especially if it gets handed down by our "superiors" in Brussels.
Meanwhile (banging once again on my worn-out old drum), many hospitals in the world still struggle on with diesel generator sets, and ECG recorders "earthed" via the plumbing (not to mention lack of a decent water supply, and all the rest).
