CONFIGURING THE PRINTER
You must configure the printer before printing with it. This chapter
describes the configuration commands.
Selecting Operating Modes
The printer works in either online or buffer mode. In online mode, the
printer prints characters as soon as they are received. In buffer mode, the
printer receives and stores characters, and then prints them upon receipt of
an EOT control character (
4 hex).
Command Description
ESC-'P'-'#' Selects online mode.
ESC-'P'-'$' Selects buffer mode.
Setting the Print Contrast
The print contrast depends on the battery voltage and the print contrast
setting. The print contrast setting also affects the print speed. A high
contrast indicates a slow speed and vice versa.
We recommend designing your
applications so the user can adjust
the print contrast.
Command Description
ESC-'P'-<value> Sets the print contrast.
<value> 0-9 0 is the highest contrast and 9 is the
lowest contrast. The default is 5.
