An ink cartridge for a compact printer module comprises a stationary printhead, an ink reservoir, a motive means and an image storing means, all housed within an elongate body. The motive means carries a printable media past the printhead which prints a full width image in a single pass. A power supply is also preferably housed within the elongate body. The body is preferably cylindrical and approximately the size of a large pen. The printhead is suitably a monolithic drop-on-demand inkjet printer.
