MICR Parsing
This section describes MICR parsing in detail and includes several
examples of useful parsing variations. It also describes how to create a
parsing format and how to create and maintain an exception table.
Define Parsing Format, Save in NVRAM
ASCII : ESC w P d1 d2 … dn 0D
Hexadecimal : 1B 77 50 d1 d2 … dn 0D
Decimal: 27 119 80 d1 d2 … dn 0D
Defines and saves parsing format. See Parsing Parameter String
Options in this document. Send with this command the parse data that
is to be the default parse string at printer power-up. If no parameters
are selected, parsing is not performed.
d1 through dn are the parse string. The string must be CR terminated.
If the string has invalid characters in it or is too long, the printer will
store a null string, and raw MICR data will be returned.
Define Parsing Format, Do Not Save Permanently
ASCII : ESC w p
Hexadecimal : 1B 77 70
Decimal: 27 119 112
Defines, but does not save parsing format. See Parsing Parameter
String Options in this document. Send this command as often as
desired to change the previous parse format string. The data sent with
1B 77 50 will be restored at power-up.
Exceptions:
If no parameters are selected, parsing is not performed.
