Comparing the two tables above there is a noticeable difference in the amount of data

saved by compressing the commands. In general, three bytes for each combined

command will be saved. This becomes significant with larger, more complex labels,

especially if the labels will be stored in the printer as macros.

Enable/Disable Barcode Autoprint

The following command will enable or disable human readable autoprint of the barcode

data:

<ESC>$b#A 0x1b 0x24 0x62 <0|1|2> 0x41

The command will affect only those barcodes with a human readable component. The

following arguments are valid:

0 – Disable human readable text

1 – Enable human readable text

2 – Enable human readable with checksum information

Note: The autoprint field is considered part of the barcode object. It is implied that when

the height of the barcode is specified, the height of the autoprint is included in that

barcode height. For example, if a Code 3 of 9 barcode is selected with autoprint in the

normal orientation and has a height of 1 inch, the height is measured from the top of the

barcode to the baseline of the autoprint text.

<ESC>&a270P

Set the writing direction to 270 degrees counter

clockwise from horizontal

of data: 9876543210

<ESC>&0P

Set the writing direction at 0 degrees.

<ESC>&a720H Set the horizontal cursor position to 720 decipoints

<ESC>&a540V

<ESC>$b1061C

Select barcode number 1061 (Interleave 2 of 5)

<ESC>$b360H

Set the barcode height to 180 decipoints (¼ inch)
