The inventive ink jet printing system is driven from a repertoire data storage medium such as perforated tape or cards, magnetic tape or cards, or the like, on which the stored data may be changed, updated, increased or decreased, or deleted in whole or in part. The data read from this storage medium is fed into a microprocessor which directs a ganged multiplicity of ink jet printing heads, to simultaneously printout a plurality of lines of type. A transport mechanism picks up and feeds paper, magazines, or the like through a printing station where the ganged ink jets print out responsive to the data supplied from the repertoire storage medium. A number of housekeeping functions are carried out simultaneously, to insure that ink is delivered to and collected from the nozzles of the printing heads.
