Printing Rates
Printing speed of text is measured in lines/minute, and is a function of the
selected font and dot density. Printing speed is independent of the number of
characters configured in the character set repertoire. Print rates for lines
containing attributes such as bold or emphasized printing, superscripts,
subscripts, or elongated attributes will decrease to not less than half the rates
of the font without such attributes. Typical printing rates for text are charted
in Table B–1.
Plotting speed of graphics is measured in inches/minute, and is calculated as
follows:
Shuttle Speed x Vertical Density

To prevent damage from overheating when graphics plotting is done over
extended periods, the hammer bank contains a thermal sensing feature that
automatically reduces the print rate.
