at the speed of your typing. In the immediate-printmode, 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.
