DC4 DC4 ESC ! n 6 p EM

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

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

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

symbol’s height; the check-digit will never show on HRC string. If f field

takes value 0, the symbol’s encoding will print at full height.
