W Immediate-print

This printer can print at the quick rate of 240 characters per second. But it will also print more slowly at the speed of your typing. In the immediate-printmode, the printhead 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.

20A$="" : INPUT u TYPE A CHARACTERS",A$

30IF A$="" THEN 50

40LPRINT A$; : GOT0 2Jl

50LPRINT :LPRINT CHR$(27);"@"

Now type several characters, and after each press the RE- TURN 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.

nAdjusting the width of space between characters

This printer provides a command that adjusts the space between all characters that it prints in the Standard mode. The < ESC > CHR$(32) CHR$(n) command adds blank space between the characters. The units of space that are added vary in l/240-inch units.

. Try this program to see how this works.
