A printer has a platen top unit fastened above the platen unit. The platen top unit is separate from the platen unit, and has first star wheels and second star wheels disposed on parallel horizontal frame members extending perpendicularly to the media conveyance direction above the platen surface. The first star wheels and second star wheels prevent the continuous paper conveyed over the platen surface from lifting away from the platen surface.
