If 10-digit strings are received and the ocheck-digit is missing or takes NULL value, question
marks are printed in place of HRC string, if possible. If the ofield takes a value of 1, a default
0 System-Digit is automatically inserted by the printer and the 12th digit is also inserted as
result of he internally available algorithm applied to the final string.
If the final UPC-A string cannot be compressed to an 8-digits string, or the received System-
Digit is different than 0 or 1, question marks are printed in place of the HRC string, if
possible.
The LEFT and RIGHT delimiters, System-Digit, and the Check-Digit are printed as
descending bars to make a field to host a 6-digits HRC string. The System-Digit HRC to the
left of the LEFT delimiter (at about the middle of the symbol) when the ffield is missing or set
to 1. In this case, the Check-Digit shows in HRC to the right of the RIGHT delimiter (at about
the middle of the symbol), when ofield takes values 2 or 3. Otherwise it never shows on the
HRC string.
UPC-EAN 2 DC4 DC4 ESC ! n5pEM
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 3rd 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 3rd 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 ocheck digit field is missing or takes NULL value, question
marks are printed in place of the HRC string, when possible. If the ofield 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 ffield 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 ffield takes a value of 0, the symbol's encoding prints at full
height.
UPC-EAN 5 DC4 DC4 ESC ! n6pEM
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 ocheck-
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
ocheck digit option takes a value of 1, the 6th 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 ocheck digit field is missing or takes a NULL value,
question marks are printed in place of the HRC string, if possible. If the ofield 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 ffield 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 ffield takes a value of
0, the symbol’s encoding prints at full height.
CODE GP DC4 DC4 ESC ! n10pEM
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.
