Patent attributes
A printing device includes: a conveying unit; a printing unit; a detecting unit; a partial printing unit; a reverse conveying unit; a printing state detecting unit; and a restoration process executing unit. The conveying unit conveys a recording medium in a conveying direction to a prescribed printing position. The printing unit is capable of printing an image based on inputted print data on the recording medium conveyed to the printing position. The detecting unit is capable of detecting the recording medium on an upstream side of the printing position of the printing unit with respect to the conveying direction. The partial printing unit controls the printing unit to execute a printing operation based on at least part of the inputted print data when print data is inputted. The reverse conveying unit conveys the recording medium in an opposite direction to the conveying direction so that a printing region printed by the partial printing unit is in a detection position at which the detecting unit can detect at least part of the printing region. The printing state detecting unit controls the detecting unit to detect a printing state in the printing region conveyed to the detection position of the detecting unit by the reverse conveying unit. The restoration process executing unit executes a process to restore the printing state when the printing state detecting unit detects that the printing state in the printing region is unsatisfactory.
