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.
Code BCD DC4 DC4 ESC ! n 12 p EM
CODE-BCD 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. No internal check digit algorithm is available for this
standard: o field is meaningless.
