UPC-EAN 2 DC4 DC4 ESC ! n 5 p EM
The ADD ON-2 bar code data fields contain numeric data only. Otherwise question marks are
printed in place of the HRC string, if possible.
If 3-digit strings are received within a DC4 DC4 ESC (... EM control sequence and the o check-digit
option field is missing or takes NULL value, the symbol encodes the first 2 digits and the 3
rd
received digit is used as the check digit, even though this may affect its readability. If the o field
takes a value of 1, the 3
rd digit is matched as opposed to the internally generated check-digit.
Question marks are printed in place of HRC string when mismatched, if possible.
If 2-digit strings are received and o check digit field is missing or takes NULL value, question marks
are printed in place of the HRC string, when possible. If the o field takes a value of 1, the check
digit are computed applying the internally available algorithm to the received string in order to
properly encode the symbol.
If the f field is missing or takes a value of 1, the 2-digit HRC string is printed above the Bar/Spaces
symbol and its height is part of the overall symbol's height. The check-digit never shows on the
HRC string. If the f field takes a value of 0, the symbol's encoding prints at full height.
UPC-EAN 5 DC4 DC4 ESC ! n 6 p EM
The ADD ON-5 bar code data field contains numeric data only. Otherwise question marks are
printed in place of the HRC string, if possible.
If 6-digit strings are received within a DC4 DC4 ESC (... EM control sequence and o check-digit
option field is missing or takes NULL value, the symbol encodes the first 5 digits and the 6th
received digit is used as a check digit, even though this may affect its readability. If the o check
digit option takes a value of 1, the 6
th digit is matched as opposed to the internally generated check
digit. Question marks are printed in place of the HRC string when mismatching, if possible.
If 5-digit strings are received and the o check digit field is missing or takes a NULL value, question
marks are printed in place of the HRC string, if possible. If the o field takes a value of 1, the check
digit is computed applying the internally available algorithm to the received string in order to
properly encode the symbol
If the f field is missing or takes a value of 1, the 5-digit HRC string is printed above the Bar/Spaces
symbol and its height is part of the overall symbol's height; the check-digit never shows on the HRC
string. If the f field takes a value of 0, the symbol’s encoding prints at full height.
CODE GP DC4 DC4 ESC ! n 10 p EM
The 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, giving the possibility of producing bars and
spaces of any width that is a multiple of the basic element width. The 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. Otherwise question marks are
printed in place of HRC string, if possible.
No Human Readable Interpretation is possible No TEXT STRING below or above the bar/space
symbol can be printed. The f and o fields are ignored.
C25-3BAR DC4 DC4 ESC ! n 11 p EM
The C25-3BAR bar code data fields do not have a defined format length and contain numeric data
only. Otherwise, question marks are printed in place of the HRC string, if possible. If the o check
digit option field takes a value of 1, an internally generated check digit complying with general 2/5
family algorithm is added to the encoded string. However, it will not show on the required HRC
string.
