STACKABLE PRINTER MODULE FOR EFFECTING DOUBLE-SIDED PRINTING

摘要

A printer module includes a housing surrounding a frame. The housing defines footing holes. A print engine is housed within the housing. The print engine includes a pair of opposed print head assemblies for enabling double-sided printing on print media to be effected. Feet extend from the housing and are spaced apart to engage in respective footing holes defined in the housing of another printer module so that the printer modules can be stacked together.
