Print Rate
The print rate, in lines per minute (lpm), is a function of the number of dot rows required to
produce the character line regardless of the number of characters in the line. For example,
more dot rows are required to print lowercase characters with descenders; consequently, those
characters are printed at a slower rate. Table 1-1 describes the print rate according to type of
character printed and print mode. Complete printing specifications are provided in the ApĆ
pendix.
