A printer includes: an image former configured to form an image on a sheet based on a print job; a processor; and a memory including instructions that, when executed by the processor, cause the processor to perform operations. The operations include: comparing first time information indicating time information set for a region where the printer is allowed to be present and second time information indicating time information in a region where the printer is currently present and determining whether a time difference between the first time information and the second time information is greater than a predetermined time, and upon determining that the time difference is greater than the predetermined time, calling for execution of maintenance of the printer and selectably displaying options of the execution of the maintenance of the printer and execution of limited print processing by the image former.
