A modular printer including a housing having upper and lower covers, a first side wall and a second, opposed side wall and inlet and exit roller assemblies for feeding media through the housing. Also included is a print engine having two opposed arcuate printheads each with a radius of curvature which approximates a radius of inlet rollers of the inlet roller assembly. Each roller is at least partially received in said curvature of each respective printhead, the print engine configured to print ink followed by a fixative onto the media operatively fed between the printhead, the inlet and exit roller assemblies configured to feed the media through the housing at a predetermined rate so that said media only leaves the housing when the fixative has dried.
