Printer module with a pen-like configuration

A printer module which comprises

• a body that defines a print media feed path extending from an input end to an output end, the body also defining a feed opening such that print media can be positioned in the input end of the print media feed path;
• a pagewidth printing mechanism positioned adjacent the media feed path between the input end and the output end for printing onto print media on the media feed path;
• at least one modular connector arranged on the body to permit at least an image processing module to be connected to the body;
• and
• a bus that interconnects the printing mechanism and the image processing module to facilitate communication between the printing mechanism and the image processing module;
• wherein,
• the body is elongate, substantially cylindrical and dimensioned to be generally pen-sized.
