6. MICR Commands

The following are the key PJL and PCL commands required to access MICR resources
in the printer. For more information on PJL and PCL languages, contact Source
Technologies Technical Support for the most current version of 's Printer Languages and
Interfaces Technical Reference documentation.

PJL MICRJOB

The MICRJOB command (@PJL MICRJOB) forces Copy count=1 and Jam
Recovery=OFF. In addition, if your MICR printer has been custom configured to support
both standard and MICR cartridges, the MICRJOB command will request a MICR
cartridge and Image Unit to be installed. The function of the MICRJOB PJL command
supports both SET and DEFAULT PJL options. An older version of the @PJL MICRJOB
without a SET or DEFAULT is still supported and functions similar to the SET command.
SET and DEFAULT formats for the MICRJOB command
There are two formats of the SET MICRJOB command
@PJL SET MICRJOB=ON
@PJL SET MICRJOB=OFF
The ON value must be included with the MICR printing application data stream.
The OFF value can allow a particular job to be processed as a non-MCR job if
the DEFAULT MICRJOB=ON was the current status of the printer.
There are two formats of the DEFAULT MICRJOB Command
@PJL DEFAULT MICRJOB=ON
@PJL DEFAULT MICRJOB=OFF (factory default)
The ON value forces all jobs to be treated as MICR jobs. This command format
allows users who cannot embed MICRJOB into their MICR printing application
data stream to send MICRJOB separately. For example, the user could send the
command in a flat file totally separate from the printing application. Once set, the
printer is now ready for MICR printing. The OFF format returns the printer to the
factory default value.
Because DEFAULT commands alter information stored in non-volatile memory,
the frequency of switching between DEFAULT ON & OFF should be limited to
around 5 times daily thereby protecting the memory from early failure.

Fonts and Secured Resources

Source Technologies' secure MICR printers hold five password protected fonts in Flash
memory. The printer requires PJL commands with the correct password value to unlock
the font resources, followed by PCL commands to print the fonts. They are then re-
locked by PJL commands or by a printer power cycle.
The PJL commands to unlock the fonts must precede all PCL commands. The re-lock
PJL commands must follow the PCL commands and final form feed command. The PCL
commands can print an unlimited number of pages between the unlock and re-lock
