Barcode height
This command defines the height of the actual selected barcode:
ESC * z P1 H P1 = height in PCL units
For every barcode type an individual value is stored. The default height value for
barcode 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.
Barcode height values are selectable in the range from 0.01 inch (P1 = 3) to 10
inch (P1 = 3000).
Note: One PCL unit is the PCL scaling unit. Default is 300 units per inch. For the
Intelligent MailĀ® Barcodes the height is fixed:
- point size 10.49 for USPS IMB Standard and
- point size 9.09 for USPS IMB Compact.
Barcode data
This command specifies the barcode 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 < data > Z data = barcode data field
The barcode 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 data P1 = number of bytes in the barcode field data
Note: The number of barcode data bytes must correspond to the selected barcode
type, otherwise the command is ignored.
