Abstract: A portable terminal has a thermal head. The portable terminal includes a first sensor unit configured to detect presence or absence of a sheet, a second sensor unit configured to detect information related to a mark provided on the sheet, and a sheet determination unit configured to determine a kind of the sheet. The sheet determination unit is configured to determine a kind of the sheet based on a result of detecting information related to the mark with use of the second sensor unit after the sheet is conveyed in a reverse direction with respect to a direction of discharging the sheet.
