11.1.3 Construction of the MEAP Platform

In addition to the installation of the system software, language file, and RUI, a printer equipped with
MEAP functions calls for the installation of MEAP content, which offers functions (system services) need-
ed to run MEAP applications and class libraries needed by the MEAP applications to control the device.
It is important that the version of the system software be fully compatible with the version of the MEAP
content, calling for special care. (In the case of a mismatch, the device will not be able to run the MEAP
application.) For version information, refer to the Service Information bulletin that is released in conjunc-
tion with the system software.
