Printer Controls

Bell BEL

Causes the printer's bell to sound.

Control code: BEL

Hexadecimal: 07

CANCEL CAN

Deletes all data in the printer’s input buffer and resets the printer to power up default values. Refer to “Printer

Reset Conditions

” on page 55 for more information.

Control Code: CAN

Hexadecimal: 18

Print Contrast ESC P n

Sets the contrast, or relative “darkness”, of the characters or graphic images to be printed where 0 ≤ n ≤ 9

(hexadecimal 30-39). A value of zero provides the greatest contrast and also the slowest print speed. Likewise,

a value of nine provides the lowest contrast, but the fastest print speed. The default value is “5”.

Since contrast is greatly affected by the quality of thermal paper being used, this command allows varying

grades of paper to be printed on successfully.

In association with this setting, the printer automatically adjusts the contrast while printing in order to achieve

consistent output based on the current battery condition and print head temperature.

Example: The following escape sequence with set the printer to a Print Contrast setting of “4”.

Escape Sequence: ESC P 4

Hexadecimal: 1B 50 34

Buffer Mode ESC P #

ESC P $

Buffer Mode may be used to force the printer to “hold” data until the entire print job is received.

If Buffer Mode has been enabled, the printer continues to hold data in its input buffer until an EOT character

(Hexadecimal 04) has been received. Once the EOT is received, the printer will print the data in the input

buffer up to the EOT character.

When Buffer Mode is not enabled (default) data are printed as received.

Example 1: The following escape sequence enables Buffer Mode.

Escape Sequence: ESC P $

Hexadecimal: 1B 4D 24

Example 2: This escape sequence disables Buffer Mode.

Escape Sequence: ESC P #

Hexadecimal: 1B 4D 23

1 2 ... 25 26 27 28 29 30 31 32 33 34 35 ... 60 61
