Printing Speed

The printing speed of text is measured in lines per minute (lpm) and is a function of the selected font and
the vertical 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. The exact print rate of lines containing these attributes depends on the specific
print job, but software maximizes the throughput by dynamically determining which dot rows contain
adjacent dots and must be printed in two strokes.
The reverse paper feed capability allows the printing of multiple densities on a single line. This is useful in
printing forms and text together or in mixing different fonts on a print line. Use of multiple densities and
reverse paper feed also affects throughput.
