ABSTRACT:
An ink jet printer capable of increasing spatial resolution of a plurality of marks to be printed thereby and method of assembling the printer. The printer comprises a print head body having a nozzle block including a plurality of adjacent ink channels of predetermined pitch "P" for printing an image on a receiver. The nozzle block is slidably disposed in the print head body and thus is movable relative to the print head body. A displacement mechanism is connected to the nozzle block for slidably moving the nozzle block a predetermined distance "P.sub.1 " less than pitch P. Before the nozzle block is moved, the channels are enabled in order to eject ink droplets which have pitch P for defining a first spatial resolution of the marks on the receiver. The displacement mechanism then moves the nozzle block the predetermined distance P.sub.1 to a second position. The channels are again enabled while the nozzle block is in this second position. Additional marks are then formed intermediate the marks formed when the nozzle block was in its first position. All the marks formed on the receiver now define a second spatial resolution greater than the first spatial resolution of the marks, so that the image has increased spatial resolution.
