Abstract
In a dot matrix printer the dot density printed is controlled
by adjustably setting the printing angle of the print head at ver
tical or at some predetermined angle from the vertical. Setting
it at an angle increases the number of passes required to com
plete a line of print but allows the portion of the line of print in
the path of head travel to be completed in one pass at the de
sired dot density or with the desired degree of dot overlap. A
principal advantage of this printer is a cost reduction in the elec
tronic circuitry since all vertically adjacent dots of characters or
graphics are printed at one time.
