I have wondered if that would be a problem, but I'm sure for the quality
required, there is a solution.

Barring my usual dislike for ribbons, yes.

I'm thinking that as the paper is fed to the color printer it can be
(near) simultaneously printed on the bottom.

I believe that's built into the photo printer.

I print 100 or more prints a week and always run a Nozzle Check before
each printing session. I have an Epson 4800. Almost any paper will
work. I rotate and flip the test sheet so I get 4 nozzle checks for
each sheet. Then if there is a problem I catch it before the ink cost
is significant. I have never had a head clog during a printing
session.
