Abstract
A thermal ink jet printing module, of the type that can be removably mounted on the carriage of a printer, comprises a reservoir for the ink and a thermal ink jet printing head fixed to and communicating with the reservoir, and a housing integral with the reservoir for receiving an ink refill cartridge for supplying the spent module with fresh ink by means of a transfer element integral with the housing of the cartridge. Successive refilling of the printing module exploits the working life of the head to the utmost and reduces the waste of expensive materials. The reservoir can be refilled relatively easily, even when the user is travelling.
