MICR commands
MICR reading
These commands control the Magnetic Ink Character Recognition (MICR) check reader, including
how it parses the character strings on checks.
The section, MICR parsing, describes how to create a parsing format and how to create and
maintain an exceptions table.
Read MICR data and transmit
ASCII ESC w 1
Hexadecimal 1B 77 01
Decimal
27 119 1
Default: All data returned
Reads and transmits the MICR data and adds a carriage
return (0x0D). If no parsing format is selected with either of the define parsing format commands (see below), all
data will be returned, which is the default.
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 defined) to the host. The return
data is defined 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.
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. Exception
If no parameters are selected, parsing is not performed.
