How do I interpret this barcode ESC sequence??

Hello,

Is there anybody out there who can tell me how to interpret this barcode ESC
sequence:
<ESC>(s4p0h35vbs24671T

The thing that puzzles me is the sub-sequence "bs". Neither b

nor s is assigned a value. Does this mean that a default value

is assigned to b and s; and if so, why not just ommit b and s

if default values are used?

Thank you...
 
You can find a description on the following page:
http://www.mecsw.com/reviews/addin/barsimm2.html#ESCAPE SEQUENCES

<ESC>(s4p0h35vbs24671T

<ESC>(s = Start of pcl font selection command
4p = readable text. 4 = print text below the code
0h = readable text font. 0 = default
35v = Height of bars. 35 * 1/72 inch
b = Width of bars (no value, use default)
s = style (no value, use default)
24671T = Typeface/barcode type (and pcl command termination). 24671 = Code
39 + Mod47 check digit

The above is equivalent to <ESC>(s4p0h35v0b0s24671T, where 0 is the
default value for these parameters. The 0b sets the primary stroke
weight to medium. The 0s sets the posture to upright, width to normal,
and structure to solid. The b and s are included to reset the values
back to the default in case some previous command has changed them. For
example, a previous PCL command may have set the font selection to bold
italic and the inclusion of bs in this string will reset that back to
normal.
