A printer may include a memory configured to store print setting information. The print setting information indicates M setting values corresponding to M setting items. Each time a print request including a plurality of setting values corresponding to a plurality of setting items including the M setting items is received, a controller of the printer may be configured to store number of times information in association with received information. In a case where first number of times information is stored in association with first received information and the first number of times information indicates that the number of times the print request was received is greater than or equal to a predetermined value, the controller may be configured to store first print setting information as new print setting information. The first print setting information may indicate M setting values indicated by the first received information.
