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.
Reread MICR Data
ASCII
:ESC w R
Hexadecimal
: 1B 77 52
Decimal:
27 119 82
Resends the previously decoded MICR data to the host.
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.
