Abstract: A printer having a bridge-like frame structure with two upright members and a cross-member, and functional components mounted to the frame structure and connected to control circuitry, wherein the control circuitry is accommodated in a central control box that has a top access opening and is pivotally mounted between the upright members and underneath the cross-member so as to be tiltable into a position exposing the access opening.

Abstract: An ink jet printing system a print head containing nozzles, a replaceable ink container, an ink supply reservoir connecting the ink container to the nozzles of the print head, and a temperature control system for controlling the temperature of the ink in the ink supply reservoir, wherein the parameters T(0); &Dgr;T/&Dgr;t, which permit a determination of the optimal operating temperature for the ink are physically encoded on the ink container to be read by the temperature control system, T(0) being the optimal operating temperature at time 0 and &Dgr;T/&Dgr;t representing the temperature change of the ink over time.
