STANDARD PRINTER COMMANDS

Universal Clear

Function Resets the printer to its initial power on state,

effectively the same as cycling printer power.

Explicit Form

(ASCII)

23 23 23 23 23 67 76 69 65 82 23 23 23 23 23

Parameters None

Comments Unlike other commands, you cannot send the

Universal Clear command to the printer as a

printable ASCII string of letters and/or numbers.

Most computer keyboards do not have a character

corresponding to ASCII 23.

Although you cannot type the command directly,

the host computer can send the command if it is

programmed in a high-level language. For example,

you could send Universal Clear to the printer

using the following BASIC code:

LPRINT CHR$(23); CHR$(23);CHR$(23);

CHR$(23); CHR$(23); "CLEAR"; CHR$(23);

CHR$(23); CHR$(23); CHR$(23); CHR$(23);

CHR$(13); CHR$(10)

Universal Clear only clears unprocessed data

from memory. It will not affect a label format that

is currently being printed.
