Patent ID: 7699416

Claim:
A printing device comprising: a conveying unit conveying a recording medium in a conveying direction to a prescribed printing position; a printing unit configured to print an image based on inputted print data on the recording medium conveyed to the printing position by the conveying unit; a detecting unit configured to detect the recording medium on an upstream side of the printing position of the printing unit with respect to the conveying direction; a partial printing unit controlling the printing unit to execute a printing operation based on a part of the inputted print data that is less than the entirety of the inputted print data, when print data is inputted; a reverse conveying unit conveying 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 is configured to detect at least part of the printing region; a printing state detecting unit controlling 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; and a restoration process executing unit executing a process to restore the printing state when the printing state detecting unit detects that the printing state in the printing region is unsatisfactory, a satisfactory printing state conveying unit conveying the recording medium in the conveying direction, after the recording medium has been conveyed in the opposite direction by the reverse conveying unit, to a position downstream in the conveying direction of an original position of the recording medium before the recording medium was conveyed in reverse, when the printing state detecting unit detects that the printing state in the printing region is satisfactory; and a remainder printing unit controlling the printing unit to execute a printing operation on the recording medium based on a remaining part of the inputted print data that is not printed by the partial printing unit, when the satisfactory printing state conveying unit has conveyed the recording medium in the conveying direction downstream of the original position before the recording medium was conveyed in reverse.
