ABSTRACT:
A printing head for an ink jet printer in which a liquid reservoir is operatively associated therewith. The liquid reservoir is provided with an air inlet opening having a filter which permits the passage of air but prevents liquid flow thereby preventing the leakage of liquid out of the reservoir upon the agitation of the liquid within the reservoir.
