Print mode

When the host asserts the PRINT mode signal, the plotter can generate ASCII
characters.

ASCII characters are produced as plot patterns on a matrix through the use
of a Character Generator ROM. When one complete print line of ASCII-
coded data is received, the data is converted into plot patterns. Each character
line is executed over 40 plot scans.

The 96 ASCII characters are coded as shown in Table E.1. Control codes
are shown in Table E.2. (see Appendix E).
