Lexmark Confidential until announced PCL 5 emulation: HP 25 An example of specifying all three v parameters, using the default values for v1 and v3, with two rows is 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 data stream, Codablock F is generated properly. Improper use of the b parameters can result in a deformed and unreadable bar code from HP BarDIMM Pro. The b3 and b4 parameters are not used. HP does not use the PCL‑S "Space." Data Matrix bar code descriptors Field name Esc(s#T Type Range name N/A Default value N/A Esc(s#1B int The minimum value is 1, but the 10 dec module may be too small and unreadable. (0A hex) There is no maximum value, but larger bar codes use more memory. Description Required. 24820T. Optional. Small module height in dots (1/600 in.). Because 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). Notes: • HP BarDIMM Pro specification contains only the PCL b parameter. • The Data Matrix symbol automatically increases in size two-dimensionally. • Up to 88 numeric digits (for example, repeating 0 to 9) produces a single Data Matrix symbol. However, an 89-digit symbol morphs into a 2 x 2 Data Matrix of 4 symbols. This behavior repeats with larger data (for example, 408 to 409 digits produce a 4 x 4 symbol, and 1632 to 1633 digits produce a 6 x 6 symbol).
