CODE GP
DC4 DC4 ESC ! n 10 p EM
CODE-GP bar code allows bar codes to be
constructed from the two basic elements (BAR and
SPACE) by sending 0,1 digits: digit 0 produces a
BAR and digit 1 produces a SPACE.
These two elements may be combined in any
sequence, thus giving the possibility of producing
bars and spaces of any width that is a multiple of
the basic element width. Default bar/spaces width
is 1/60” (q = 0,1) but these values may be set by the
user according to its specific needs. Data fields do
not have a defined format length and contain 0,1
data only; question marks will be printed in place of
HRC string otherwise, if possible.
No Human Readable Interpretation is possible,
hence is the user task to provide a TEXT STRING
below or above the bar/space symbol: f field is
meaningless. No internal check digit algorithm is
available: o field is meaningless.
C25-3BAR
DC4 DC4 ESC ! n 11 p EM
C25-3BAR bar code data fields do not have a
defined format length and contain numeric data
only: question marks will be printed in place of
HRC string otherwise, if possible. If o check digit
option field takes 1 value, an internally generated
check digit complying with general 2/5 family
algorithm will be added to the encoded string:
however it will not show on the required HRC
string.
