Abstract: A printing apparatus includes a printing unit that includes an ejection port surface provided with ejection ports through which liquid is ejected, a wiping unit, a depressurizing unit, and detection unit. The wiping unit has an opening and wipes the ejection port surface by moving in a predetermined direction while the opening abuts against the ejection port surface. The depressurizing unit applies negative pressure to the ejection port surface via the opening. The detection unit detects an ejection state of the ejection ports. After driving the depressurizing unit when the opening abuts against the ejection port surface, the suction operation sucks the liquid from the ejection ports while moving the wiping unit. The suction operation is performed from a first ejection port detected as an ejection-failed ejection port by the detection unit under a suction condition different from suction conditions of the ejection ports other than the first ejection port.
