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.
