Notes
All parameters are ASCII characters, i.e. greater than or equal to 0x20,
with the exception of a non-ASCII character enclosed in single quotes
as a field separator. This applies both to parameter specifications sent
from application to printer, and to MICR data returned from printer to
application.
Parameters are positional; their order in the parameter string is the
order in which the parsed MICR data will be returned. Unrecognized
parameters will be ignored, and processing of the parsing parameters
will stop. Any data remaining after the unrecognized parameter will be
treated as normal input data.
If parameters are not defined (for example, 1B 77 50 <CR> or 1B 77 70
<CR>) parsing is not selected. One status byte followed by all decoded
MICR characters will be returned. This is the default parsing format if
no other is selected:
Status Status Byte Value

Paper jam, no data
No MICR characters, no data 0x00
