Print mode
When the host asserts the PRINT mode signal, the plotter can
generate ASCII characters. Table 5-5 shows the timing relationships
for print mode signals.
Table 5-5. Mode signals
ASCII characters are produced as plot patterns on a 16 x 20 dot
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
20 plot scans.
