Printing Rates
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.
