$ Bar code height
This command defines the height of the actual selected bar code:
ESC * z P1 H
For every bar code type an individual value is stored. The default height
value for bar code is 0.5 inch (P1 = 150) except EAN, UPC and Postnet.
The default height for EAN and UPC is defined with the scaling factor SC 2, 6
or 9. The height of Postnet is fixed.
Bar code height values are selectable in the range from 0.01 inch (P1 = 3) to
10 inch (P1 = 3000).
One PCL unit is the PCL scaling unit. Default is 300 units per inch.
Note:

$ Bar code data

This command specifies the bar code data field. Two command formats are
supported. The first format is conforming to earlier PCL3 commands and
does not report the number of data bytes in front of the data field:
ESC * z <
The bar code data are enclosed in the two brackets. If the right bracket itself
is part of the data field it has to be sent twice.
The second format is according to typical PCL5 commands. The number of
bytes in the data field is indicated before sending the data:
ESC * z P1 Z
The number of bar code data bytes must correspond to the selected bar
Note:
code type, otherwise the command is ignored.
P1 = height in PCL units
> Z = bar code data field

P1 = number of bytes in the bar code field
