ABSTRACT:
A conveying roller is disposed downstream of a feeding roller in a conveying direction and conveys a sheet of recording medium to a printing position along a conveying path. A medium detecting unit is disposed between the feeding roller and the conveying roller along the conveying path and detects the sheet of the recording medium. A printing unit performs printing at the printing position. A target-rotational-amount setting unit sets a target rotational amount for feeding the sheet of the recording medium to the conveying roller, based on a rotational amount of the feeding roller measured from when the feeding roller begins feeding the sheet of the recording medium accommodated in the feeding cassette until the medium detecting unit detects the sheet of the recording medium. A controller controls the feeding roller to continue rotating until the rotational amount of the feeding roller reaches the target rotational amount.
