7–4 Digital Emulation
If word length is 7–bits, printable characters are only generated from
columns 2 through 7. If word length is set at 8–bits, printable characters can
be generated from columns 2 through 7 and columns 10 through 15. (Note
that in an 8–bit environment, columns 0 through 7 have the 8th bit set to
zero, while columns 8 through 15 always have the 8th bit set to 1.)
NOTE: The actual characters printed may not always be those shown in the
DEC Multinational Character Set because printable characters in the
column/row positions vary, depending upon the character set used.
Control Codes
Control codes drive printer activity. Control codes do not print. The printer
recognizes two kinds of control codes:
• Control Characters
• Escape Sequences
