The ink jet print device has a multiplicity of plug-in type printheads (12) mounted on support plates (23). The support plates can be replaced and interchanged without difficulty by an operator. To this end, the print device is divided into a lower part and the actual printheads (12) such that, when the heads (12) are plugged in, the necessary mechanical, electrical, and hydraulic connections (27, 28, 29, 31, 26, 41, 33) between the heads (12) and the lower part of the print device are all established. Guide and locking means are used to ensure that the plugged-in heads are exactly positioned and held in place. The sockets for the individual heads (12) are each of identical design so that the simple replacement concept permits any printheads to be used for color printing and graphics and for printing with different droplet sizes.
