Any one of 17 fonts may be selected from the five available print modes. Each font
may be used exclusively or intermixed within any given line. When a mode change
is indicated, data already input is printed in the mode first selected, the printer skips
a few spaces, changes mdoes, and then receives new data.
Speed of printout (CPS) is slightly different in each mode depending on operational
complexity, e.g., the bold print and double-strike mdoes are created with two passes
of the printhead, thus requiring a slightly greater printout time.
See the “Detailed Summary of Character Fonts” Table on page 2 for print
specifications and CPS for each mode.
