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.

Calibrate Blackmark Sensor

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.

Note • Be sure to first set up the length of the black mark and the distance between two black marks in the parameter setup.

ESC # is available in hardware revision B or higher.

	ESC Z		Go to next Top of Form
1B	5A	Hex
27	90	Decimal

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).
