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. Table 11 lists typical printing rates.
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.
