An image forming apparatus includes an operation unit that receives an instruction for an operation and executes the operation, and an instruction unit that outputs the instruction to the operation unit. The operation unit includes a configuration storage unit that stores deployment configuration of one or more image forming apparatuses, and an instruction acceptance unit that accepts an instruction for an operation corresponding to the deployment configuration. The instruction unit includes an instruction output unit that receives a designation of an operation, and outputs an instruction for the designated operation to the operation unit, and a configuration reporting unit that, if the designated operation does not correspond to a first deployment configuration stored in the configuration storage unit, reports to the operation unit a second deployment configuration to which the designated operation corresponds, and stores the second deployment configuration in the configuration storage unit, before the instruction is output.

Provided is a printing device including a print data receiving unit, a page calculation unit that calculates a number of pages before stopping with using a page length of received print data and a distance from a printing mechanism unit to a visual recognition unit, a print instruction unit that changes the number of pages before stopping or a number of printed pages and performs print processing when the received print data corresponds to a control page for controlling printing, and a print stop unit that stops printing when the number of printed pages coincides with the number of pages before stopping.

A history storage device includes: a storage unit that, in storing first history information including phenomenon information corresponding to a phenomenon having occurred and accompanying information accompanying the phenomenon information in a storage region, when the phenomenon information included in the first history information is duplication of phenomenon information included in second history information having already been stored in the storage region, deletes the phenomenon information included in the first history information and stores, in the storage region, the accompanying information which is included in the first history information and is associated with the phenomenon information; and a reconstruction unit that, in reading out the first history information from the storage region, based on the phenomenon information with which the accompanying information included in the first history information is associated, reconstructs the deleted phenomenon information, to thereby reconstruct the first history information including the phenomenon information and the accompanying information.
