Beschreibung
Zusammenfassung:	A printhead control circuit outputs a first signal to a second wire while a first wire coupled to a first terminal is being supplied with a first voltage signal; outputs a second signal to the second wire coupled to a second terminal while the first wire is being supplied with a second voltage signal; outputs a third signal to the second wire while a third wire coupled to a third terminal is being supplied with a third voltage signal; outputs a fourth signal to the second wire while the third wire is being supplied with a fourth voltage signal; and thereby causes the printhead to perform abnormality detection in response to the first to fourth signals and the first to fourth voltage signals.
