Abstract
In a nonimpact printer having a reciprocable printer head, ink is supplied to the head through a pair of identical, flexible conduits which are connected from first and second spaced apart outlets of an ink container. The container is not air tight with the outside so that it can act as a pressure absorber. Each of the first and second conduits have a sufficient length to allow the head to reciprocate along the length of a platen with end of each conduit moving therewith to cause pressure variations to occur in the conduits when the printer head varies its speed of movement. By virtue of the pressure absorbing action of the liquid container, the pressure variations are nullified and the printer head is supplied with constant pressure ink.
