MSI bar code data fields do not have a defined format length and must contain
numeric data only: question marks will be printed in place of HRC string
otherwise, if possible. To releaf the host from calculating MSI check digits,
internal algorithms are provided that are accessible by the host application
program giving the proper supported value to o check-digit option field, according
to the following options:
0 Print the bar code symbol with
no printer-generated check
digits
1 Print the bar code symbol with
IBM Modulus-10 check digit -
generated by the printer and
put at the end of the numeric
string: this will be the 2
nd
check digit, the 1 st check digit
is IBM Modulus-10 also.
2 Print the bar code symbol with both
check digits generated by the printer
and put at the end of the data. The 2
nd
check digit is IBM Modulus-10, the 1 st
check digit is IBM Modulus-10 also.
3 Print the bar code symbol with
both check digits generated by
the printer and put at the end
of the data. The 2
nd check digit
is IBM Modulus-10, the 1 st
check digit is NCR Modulus-11:
if modulus is 10, it is an error
and question marks will be
printed in place of HRC string,
if possible.
4 Print the bar code symbol with both
check digits generated by the printer
and put at the end of the data. The 2
nd
check digit is IBM Modulus-10, the 1 st
check digit is IBM Modulus-11: if
modulus is 10, it is an error and
question marks will be printed in
place of HRC string, if possible.
