I can't give you the details but it shoul be possible.
You'll have to do some reading on writing udev rules,
there are resources on the web about that. AFAIK you
can run arbitrary scripts from udev.

Find the udev rule that loads the modules when the printer is
switched on, and modify it so it calls a script (probably in
the background) that loads the module (modprobe), waits for
some seconds (sleep) and the removes the module (rmmod).
