An output control apparatus is used in an output apparatus adapted to form image
data by analyzing an instruction received from an external apparatus and to output
thus formed image data. The output control apparatus includes a memory for memorizing,
in case of a change in the state in the apparatus, an identification code corresponding
to the change, and an instruction unit for providing a test output instruction
for instructing the output of set value information of the output apparatus. Also
included is a control unit for controlling the output, if the identification code
is memorized in the memory and in response to the instruction by the instruction
unit, in such a manner as to output information corresponding to the identification
code together with the set value information of the output apparatus.
