Printing Speed
The speed at which text prints is measured in lines per minute (lpm). This
speed is inversely proportional to the number of dot rows required to produce
a character line, regardless of the number of characters in the line. More dot
rows are required to print lowercase characters with descenders;
consequently, those character lines print at a fractionally lower rate.
The printer also prints dot–addressable graphic images. The speed at which
graphics are plotted is measured in inches per minute (ipm). Unidirectional
plotting produces slightly better print quality and takes about twice as long as
bidirectional plotting. You can select either plotting mode from the control
panel.
Printing and plotting rates also vary according to the print mode you select.
Print mode refers to the way you instruct the printer to create characters. If,
for example, you select near letter quality (NLQ) mode, the printer uses more
dot rows to form characters than if you choose high speed (HS) mode.
Character formation and print speed are faster in HS mode because the
printer prints fewer dot rows to form characters. Vertical dot density is a
factor in printing speed.
Nominal printing rates are charted in Appendix A.
