Abstract
Technology enabling accurately detected marks on a print medium according to the type of print medium is provided. A printerhas a media type identifierthat determines the type of medium; a mark sensorthat projects light and detects a mark on the medium; and an emittance controllerthat sets the emittance level of the light the mark sensorprojects. The printercan change the operating mode according to the type of medium M identified by the media type identifier. In the white medium mode, the mark sensordetects a mark MR with the emittance level set to a white medium emittance level. In the non-white medium mode, the mark sensordetects a mark MR with the emittance level set to a non-white medium emittance level, which is higher than the white medium emittance level.
