Software Command Syntax
The commands in this section are grouped after what they do, and these groups are sorted in a
theoretical usage sequence. It starts with commands for specifying the printed page — through
text-and-graphics commands — to cut-and-present commands. System and status commands
are presented at the end.
Black Mark (Top-Of-Form) Commands
See also Aligning Preprint and Thermal Print on page 89 .
Refer to TTP 2000 Technical Manual (Zebra part number P1002902) for correct format.
Looks for a black mark, measures the contrast of the mark and sets parameter n51 to a suitable
value for the detected voltage, then reverses to the start position.
To make the calibration permanent, send <ESC>&<4>, store parameter values.
ESC # is available in hardware revision B or higher.
In black mark mode, an ESC Z starts looking for a black mark at the current position and
continues for one page length. If no black mark is found, the printer stops and bit 3 in status
byte 2 is set to 1 (See ESC ENQ 6
page 59 ).
When black mark mode is disabled, ESC Z will perform a form feed without cut (disregarding
the setting of parameter
34 on page 80 ).
