CHAPTER
3
PROGRAMMING
The character size switches to 10 characters per inch
(CPI)
after the
printer receives the DC2 command. The character size becomes 12
CPI
when the
ESC:
command
is
received and 17.1
CPI
when the
51
command
is
received.
NOTE:
When
the
power
is
turned on while the
TOF
switch
is
depressed, the printer
is
set to 17.1
CPl.
You
can also set the printer to 17.1 CPI at power ON by setting
internal switch
2 to the condensed print mode.
The
printer will print in 17.1
CPI
until
power is turned OFF
or a command
is
sent to change the character size.
You can
double
the
width
of
10-, 12-, and 17.1-CPI print by insert-
ing the
US
command after the character size you want doubled. This
command doubles the size
of
characters that
follow
the command
on one line. The DC4 command can also
be
implemented on the
same line
as
an
SO
command. The DC4 command cancels double-
width
printing before the end
of
a line. This enables you to em-
phasize specific words
or
characters
within
a single line, and to
automatically return to your preselected type size.
The
ESC
W 1 and
ESC
W 0 commands override both DC4 and
SO
commands, and can
be
utilized to either permanently
implement
or
cancel
double-width
printing
within
a program
or
document. The
ESC
W 1 command implements
double-width
printing; the
ESC
W 0
command cancels it.
Character size can be changed in the
middle
of
a line unless
your
software package does
not
allow
you to
do
that. The table
below
in-
dicates the
maximum
number
of
characters per line in each character
size:

NOTE: Some forms
of
BASIC will
not
allow you to print more than
80
characters on
a line. Check your BASIC manual to see
if
you can override this limitation by using a
WIDTH
statement.
