at the speed of your typing. In the immediate-print mode, the
print head prints one character
at a time, as you send it. The
printer also moves the paper up so that you can see the current
line and then down to continue printing.
You can turn the immediate-print
mode on with (ESC) "i" 1.
Before looking at it, let's review the normal operation
of the
print buffer. Enter this program.
20 A$="" : INPUT ' TYPE A CHARACTERS ",A$
30 IF A$="" THEN 50
40 LPRINT A$; : GOT0 20
50 LPRINT :LPRINT CHR$(27);"@"
Now type
several
characters,
and after
each press
the
RETURN
key. The printer simply puts the characters
into its
buffer while it waits for a carriage return code. (In this program
the RETURN key doesn't send a carriage return code.) To end
this program
and print
the contents
of the buffer,
press
RETURN alone.
Now add this line:
10 LPRINT CHR$(27);"il";
And RUN the program. Your printer will now respond to your
typing - immediately.
When you are finished, press RETURN
alone.
W Adjusting the width of space between characters
This printer provides a command
that adjusts the space be-
tween all the characters
that it prints with the Standard mode.
The (ESC) CHR$(32) CHR$(n) command adds blank space be-
tween the characters.
The units of space that are added vary
with the print pitch you are using, as shown in Table 6-2.
