Transmit last MICR read
ASCII: ESC w R
Hexadecimal: 1B 77 52
Decimal: 27 119 82
Resends the previously decoded MICR data (as if the parsing has not been dened) to the host. The return
data is dened in the “Read MICR data and transmit” command (1B 77 01) without parsing and presents the data from
the last MICR read since power-up or reset or indicates in the status that no read has yet occurred.
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.
Dene parsing format, save in NVRAM
ASCII: ESC w P d1 d2 … dn CR
Hexadecimal: 1B 77 50 d1 d2 … dn 0D
Decimal: 27 119 80 d1 d2 … dn 13
Denes 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 unparsed MICR data will be returned.
Dene parsing format, do not save permanently
ASCII ESC w p
Hexadecimal 1B 77 70
Decimal 27 119 112
Denes, but does not save parsing format. See parsing parameter string options in this document. Send as often as
desired to change the previous parse format string.
If no parameters are selected, parsing is not performed.
Same parameters as 1B 77 50....
