ABSTRACT:
An apparatus having a reservoir for enclosing a fluid and a valve for selectively applying gas under pressure to said reservoir and venting said reservoir to the ambient air. A controller supplies a pulse of predetermined duration selected from a plurality of durations to actuate the valve to apply the gas under pressure to the reservoir for expelling a predetermined amount of ink therefrom through a tube by compensation for dynamic effects. The ink is transferred from one end of the tube to a selected item of a sheet of items by moving the end of the tube closely adjacent to the sheet while the ink is being expelled from the reservoir and through the tube for transfer to the individual item.
