Two-dimensional bar codes
32
The requested number of rows (V2 parameter) must be specified when using the HP BarDIMM Pro
version 3.3A. The following default PCL with no parameters are invalid:
• Esc(s24840T—This does not work on HP; the row parameter must be specified.
• Esc(s16,2v24840T—This works on HP; default line bar height with two rows are specified.
• Esc(s,2v24840T—This works on HP; the default line bar height is specified.
The following is an example of specifying all three V parameters, using the default values for V1 and
V3, with two rows:
• Esc(s16,2,20v24840T
HP documents the bar widths (B parameter) in their reference manual, but varying B1 or B2 does not
affect the bar width of the symbol. When B1 is specified in the datastream, Codablock F is generated
properly. Improper use of the B parameters can result in a deformed and unreadable bar code from
HP BarDIMM. The B3 and B4 parameters are not used.
HP does not parse or use the PCL S “Space”.
Bar code descriptor for Data Matrix
Notes:
• HP BarDIMM specification contains only the PCL “B” parameter by itself.
• The Data Matrix symbol automatically increases in size two-dimensionally.
• Up to 88 numeric digits (i.e., repeating 0–9) produces a single Data Matrix symbol. However,
an 89-digit symbol will morph into a 2x2 Data Matrix of 4 symbols. This behavior repeats with
larger data (for example, 408 to 409 digits produce a 4x4 symbol, and 1632 to 1633 digits
produce a 6x6 symbol).
Field Name Type Range
Default
(if not specified)
Description
Esc (s#T name n/a n/a Required
24820T
Esc(s#1B int Minimum:
Minimum value is 1, but
the module may be too
small to be readable.
Maximum:
There is no maximum
value, but larger bar
codes use up more
memory.
10 (dec) or 0A (hex) Optional
Small module height in
dots (1/600 inch).
Since the Data Matrix
modules are square,
this parameter also
determines the small
module width.
Note: Using a value of 0
is the same as using a
value of 10 (default).
