ABSTRACT:
Ink contained in a pen reservoir (12) is subject to the capillarity provided by an array of spaced apart capillary members (10). The capillarity provided by the capillary members (10) is sufficient for establishing a back pressure at the print head (18) of the pen (14) to thereby avoid leakage of ink from the reservoir (12) whenever the print head (18) is inactive.
