Abstract: A terminal device includes a first communication device, a display device, and a first control device. The first control device functions as a display controller. The display controller allows the display device to display a first massage in a message display area of the display device. When the first message is not a high-importance message and the display controller then receives through the first communication device a second message sent from the information processing apparatus, the display controller allows the display device to execute first processing of scrolling a displayed image in the message display area and displaying the second message in the message display area. When the first message is a high-importance message and the display controller then receives the second message through the first communication device, the display controller allows the display device to execute second processing different from the first processing.

Abstract: A password authentication device includes a period information storage unit, an acquirer, an authentication unit, and an updating unit. The acquirer acquires the period information when the user inputs a password. The authentication unit authenticates the user when a difference between the reference value stored in the period information storage unit and the period information acquired by the acquirer is equal to or less than a specified value. The updating unit updates the reference value of the period information stored in the period information storage unit based on the period information acquired by the acquirer. The password input period indicates a period from when the user starts inputting the password until the user completes the input. The depression period proportion indicates a proportion that a depression period occupies the password input period. The period-between-characters proportion indicates a proportion that a period-between-characters occupies the password input period.

Abstract: An image forming system includes: a first notification processing portion that notifies, of a shortage of a consumable, a user of an information processing apparatus that is a transmission source of a first print job which is, among print jobs stored in a storage portion, a print job for which the consumable necessary for execution of the print job will become insufficient during a stop possible period of the print job, the stop possible period being a time period in which execution of the print job can be stopped; and a second notification processing portion that notifies, of the shortage of the consumable and presence of the first print job, a user of an information processing apparatus that is a transmission source of a second print job which is, among the stored print jobs, executed later than the first print job in the execution order and uses the consumable.
