Specifications

At the end of the travel of the shuttle motor, the paper is advanced by
1/72-inch (approximately one dot diameter), and the next row is printed
in the reverse direction. In NLQ printing the paper is not advanced
until the actuators have travelled back across the same line reprinting
the same dots.
To build up a character the dots must be precisely located. This is
achieved by developing a position signal derived from a Linear Velocity
Transducer (LVT) attached to the actuator assembly.
The size and font of the chosen print affects the printing speed.
Figure 2–3 illustrates the formation of characters in Data Processing
font.
