ADD ON-5 bar code data fields contain numeric data only: question marks
will be printed in place of HRC string otherwise, if possible.
If 6-digit strings will be received within a DC4 DC4 ESC (... EM control
sequence and
o
check-digit option field is missing or takes NULL value, the
symbol will encode the first 5 digits and the 6
th
received digit will be used as
check digit, even though this may affect its readability; if
o
check digit option
takes 1 value, the 6
th
digit is matched versus the internally generated check-
digit an question marks will printed in place of HRC string when
mismatching, if possible.
If 5-digit strings will be received and
o
check digit field is missing or takes
NULL value, question marks will be printed in place of HRC string, if
possible; if
o
field takes value 1, the check digit will be computed applying
the internally available algorithm to the received string in order to properly
encode the symbol.
If
f
field is missing or takes value 1, the 5-digits HRC string will be printed
above the Bar/Spaces symbol and its height will be part of the overall
symbols height; the check-digit will never show on HRC string. If f field
takes value 0, the symbols encoding will print at full height.
