An example image forming apparatus includes a communication device to communicate with an external apparatus, a printing engine to perform a printing job, and a processor to, based on receiving a printing request for the printing job, perform accounting processing for the printing job, and control the printing engine such that the printing job is performed. The processor, based on an error occurring in the printing job, is to control the communication device to transmit proceeding history information of the printing job and accounting information to another image forming apparatus.

An image processing apparatus includes an image processing section that processes an image, a plug-in adding section that adds a plug-in, the plug-in being a function executed in corporation with the image processing section, an additional-charging-information adding section that adds additional charging information as the plug-in is added by the plug-in adding section, the additional charging information being set for a job included in the plug-in, and a charging section that charges for a job on a basis of the additional charging information, in a case where the job to be executed is included in at least one job included in the additional charging information and the job to be executed is executed.

An image forming apparatus includes a management application and a common application. The management application manages a counter. The common application is other than the management application. The management application causes the image forming apparatus to function as: a counter managing unit that manages the counter that counts a count of executions of specific processing by the common application; and an execution count unit that counts the count of executions using the counter managed by the counter managing unit.

A printing and copying system is provided that includes a server configured to manage user account information related to a user, and an apparatus connected to the server, the apparatus configured to send a printing request or a copying request to the server. The user account information includes a plurality of wallets associated with the user, and the plurality of wallets each represent funds available to the user. The server is configured to determine whether to authorise the printing request or copying request based on the funds available in the plurality of wallets.

A printing apparatus determines whether a charging function is set to be enabled. If the charging function is set to be enabled, the printing apparatus prohibits use of a direct wireless communication mode.

The direct marketing system and method is disclosed that receives information from two parties, referred to as the sending party and the receiving party, and delivers a message or advertisement between the two. The message is then immediately printed on the receiving party's printer, and a small fee is paid by the sending party. A portion of this fee is sent to the receiving party as reimbursement for paper costs, ink costs, and printer maintenance.

An information processing apparatus includes an obtaining unit and a display controller. The obtaining unit obtains pieces of identification information for identifying plural target devices that cooperate with each other. The display controller controls display of a cooperative function that is executed through cooperation between the target devices identified by the pieces of identification information.

An information processing apparatus includes a receiving unit and a display controller. The receiving unit receives designation of a cooperative function that becomes available through cooperation among a group of devices. The display controller controls display of information about a result of extracting the group of devices that are necessary to use the cooperative function.

There is provided a printing system. A reward information memory stores reward identification information and an upper limit amount in association with each other. A set charge memory stores a usage charge for each print setting. A specification unit obtains an upper limit amount in association with the input reward identification information from the reward information memory, and specifies selectable print settings within a range of the upper limit amount from the information stored in the set charge memory. A controller controls the execution of printing so as to be executed with the print settings specified by the specification unit.
