Software Command Syntax

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.

Page Setup

Page setup is performed with parameters instead of dedicated commands. This makes it possible to store the setup in the non-volatile parameter memory. To minimize doubling of functions the page setup commands have been removed from this manual. The parameters to use are described under Printable Area on page 86.

Black Mark (Top-Of-Form) Commands

See also Aligning Preprint And Thermal Print on page 87.

ESC #

1B 23 n1	Hex
27 35 n1	decimal

Calibrate Blackmark Sensor

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.

Important • 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

1B 5A	Hex
27 90	Decimal

Go to next Top of Form

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, bit 3 in status byte 1 is set to 1 and the printer will report NAK 0A on the next status query.

When black mark mode is disabled, <ESC>Z will perform a form feed without cut (disregarding the setting of parameter 34).
