You can turn immediate-print mode on with (ESC) “i” 1. But
before looking at it, let’s review the normal operation of the
print buffer. Enter this program.
20 A$="" : INPUT
" TYPE A CHARACTER ",A$
30 IF A$="" THEN 50
40 LPRINT A$; : GOT0 20
50 LPRINT
: LPRINT CHR$(27);"@"
Now type several characters, and after each press the
RETURN key. True to form, the printer just stuffs the
characters into its buffer while it waits for a carriage return
code. (In this program the RETURN key doesn’t send a car-
riage return code.) To end this program and print the contents
of the buffer, press RETURN alone.
Now add this line:
10 LPRINT CHR$(27);"il";
And RUN the program. Your printer responds to your typing -
immediately.
’
When you are finished, press RETURN alone.
n Adjusting the width of space between characters
This printer provides a command that adjusts the space be-
tween the NLQ characters that it prints when the DIP switch l-
6 is set on. The (ESC) CHR$(32) CHR$(n) command adds blank
space between the characters. The units of space that are added
vary in l/60-inch units.
Try this program to see how this works.
