Abstract: PROBLEM TO BE SOLVED: To reduce the effect of a parasitic current passage occurring in a switching matrix for controlling the ejector in an acoustic ink printer. SOLUTION: In a switching matrix 60, a non-select column is connected with a column compensation bus 54 through a capacitor 52. When a transducer 20a at row 0 and column 0 is selected, for example, a current flowing from row 12a to a column other than column 0 is drawn out from that column to the column compensation bus 54. Consequently, the current flowing through a parasitic current passage returning from that column to column 0 (e.g. a passage comprising transducers 20d, 20e including the signal line 12b of that column other than row 0) is reduced.
