Provided are a print head inspection method, a printing method, a print head inspection device, and a printer, with which it is possible to accurately detect faults in a recording element in a short time. A plurality of recording elements provided to a print head are divided into a plurality of groups, an inspection order is set by group unit, and inspections of the recording elements are performed periodically in group units according to the set inspection order. If, as a result of the inspection, a recording element is detected to have a fault, the recording element in which the fault was detected is designated for reinspection, the inspection order is changed by an interrupt, and reinspection is performed for the group including the recording element designated for reinspection. If, the recording element designated for reinspection is again detected as having a fault as a result of the reinspection, the recording element is designated as an irregular recording element.
