Note that we didn’t hnvc to re-enter the download characters, since they were already sent to the printer with the first pro- gram. They will stay with the printer until you download new characters to replace them or turn the printer off. Even the (ESC) “@” command, which initializes the printer, does not destroy the contents of download RAM.

nHow to print the characters in control code area

As explained earlier, you can define characters with ASCII values below 32. But you cannot printout those characters with normal usage. This is inconvenient to us, even we can define download characters in that range. So, we have made a com- mand to print those characters:

(ESC i “I” CHR$(z)

This command is used to print the characters (if n = 49) or to select as the control codes (if n = 48). Let’s try it out. Enter this program:

10 LPRINT CHR$(27) ;“xO”;

20LPRINT CHR$(27);“&“:CHR$(O);CHR$(7);CHR$(7);

30FOR M=l TO 30

40READ MM

50LPRINT CHR$(MM);
