## Abstract

An ink-jet printing module is used for a page-width array ink-jet printer. The ink jet printing module includes a page-width array platen and a plurality of ink-jet cartridges. The page-width array platen has a plurality of receiving cavities arranged as an array. Each of the ink-jet cartridges is detachably and independently embedded into one of the receiving cavities, and includes a body for storing ink, an ink-jet chip to be driven for ejecting the ink, a plurality of nozzles disposed on the ink-jet chip, and a control node for receiving signal to drive the ink-jet chip. The ink-jet chip is disposed on a bottom of the page-width array platen and is driven to eject the ink through the nozzles onto a printing medium.
