Abstract: A print speed setting system includes an information processing system and an image forming apparatus capable of varying a print speed. The information processing system generates key data based on unique information unique to the image forming apparatus and a designated print speed of the image forming apparatus, and outputs the generated key data. The image forming apparatus acquires the key data input by a user operation, specifies the designated print speed based on the acquired key data and the unique information of the image forming apparatus, and sets a print speed of the image forming apparatus to the specified designated print speed.

Abstract: A print speed setting system includes an information processing system and an image forming apparatus capable of varying a print speed. The information processing system generates key data based on unique information unique to the image forming apparatus and a designated print speed of the image forming apparatus, and outputs the generated key data to a mobile terminal capable of wirelessly communicating with the image forming apparatus without passing through other communication devices. The image forming apparatus acquires the key data from the mobile terminal, specifies the designated print speed based on the acquired key data and the unique information of the image forming apparatus, and sets a print speed of the image forming apparatus to the specified designated print speed.

Abstract: An authentication system includes a user authentication unit. The user authentication unit performs user authentication by combining password authentication and handwriting authentication, the password authentication being performed by collating an entire character string of a password inputted using an operation input unit and a handwriting input unit with an entire character string of a registration password stored in a storage unit, the handwriting authentication being performed by collating the handwriting information of a part of characters of the password inputted by the handwriting input unit with handwriting information of handwriting data of this inputted character stored in the storage unit.

Abstract: An image forming system includes a plurality of processing apparatuses. An image forming apparatus includes an image forming section, storage, an acquiring section, a first specifying section, a receiver, a second specifying section, and a notifying section. The storage stores therein a position of each of the processing apparatuses. The acquiring section acquires state information from each of the processing apparatuses. The state information indicates whether a corresponding one of the processing apparatuses is in a normal function state or a malfunction state. The first specifying section specifies, from among the processing apparatuses, a malfunctioning processing apparatus for which the malfunction state is indicated by the state information. The second specifying section specifies a relative position of the malfunctioning processing apparatus with respect to a mobile terminal device.

Abstract: An information processing apparatus includes a generation processing portion, a presentation processing portion, and an authentication processing portion. The generation processing portion generates a password. The presentation processing portion presents, in such a way as not to pass through an external device, the password generated by the generation processing portion to a mobile terminal associated with an authentication-target user. The authentication processing portion authenticates the user when the password is input after the password is generated by the generation processing portion.
