Select Barcode Height (PCL Units)
The following will set the barcode height in PCL units with 1 decimal. The number of
codewords per line are as follows: PDF417 (0-30), Micro PDF (0-4), QR Code (0-40). For
Datamatrix it is the symbol size value per the table below.
$b#J 0x1b 0x24 0x62 0x48
If the barcode auto print is enabled prior to sending the barcode data, the height of the
barcode will include the height of any human readable text if enabled. The number of
pixels used in the barcode height will always be rounded. As an example, if the barcode
height is specified to be 97 decipoints, the number of dots used on a 300 DPI printer is
[(97 x 300)/720 = 40.417] and will round down to 40 dots. If the height is specified to be
98 [(98 x 300)/720 = 40.833] the number of dots will be 41. The default barcode height is
720 decipoints (1 inch) for linear barcodes.
Select Narrow Bar Width (Decipoints)
The following command will set the width of a narrow bar in Decipoints (720/inch) with
one decimal:
$b#M 0x1b 0x24 0x62 0x4d
An example of this command might be:
$b9.6M
This will set the width of the narrow bar to 9.6 Decipoints which is equivalent to 4 dots at
300 dpi or 8 dots at 600dpi. This command will round for example (2*300)/720 = 0.833
