A print engine assembly is provided which is mountable to an inkjet printer. The print engine assembly comprises a housing for mounting to a printer and a printhead assembly and capping mechanism mounted to the housing. The printhead assembly incorporates a printhead having a plurality of nozzles for selectively ejecting drops of ink towards a print medium passing the nozzles. The printhead further has a structure that defines a space adjacent the nozzles. The capping mechanism is used to selectively cap the nozzles of the printhead. In operation, when the printhead is in a printing mode, the structure allows drops of ink ejected from the nozzles to strike the print medium while preventing contact between the nozzles and foreign bodies larger than a threshold size, and when the printhead is in a non-printing mode, the capping mechanism is engaged with the structure to provide a closed atmosphere in the space.
