Print Rate; Plot Rate - Printronix P6000L User's Reference Manual

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 and 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
Appendix.

Plot Rate

As well as character printing, the printer is capable of dot addressable graphic plotting. Based
on the protocol selected, either P-Series Plot Mode or Serial Matrix Bit Image Graphics is
used; the plot rate specifications apply to both P-Series and Serial Matrix types of graphic
plotting. The plot rate (in inches per minute, ipm) is described in Table 1-2 according to the
dot density (in dots per inch, dpi). Complete plotting specifications are provided in Appendix
C.
DENSITY (dpi)
