ABSTRACT:
A spirally interlacing jet drop recorder prints gray tones on a recording sheet mounted upon a rotating drum. The number of jets and the jet spacing is selected in such a manner as to facilitate time sharing of a matrix pattern memory by control circuits controlling operation of each of the jets. Matrices representing the gray levels to be produced are progressively printed from column to column by different ones of the array of jets.
