摘要 PURPOSE: To prevent the decrease of the printing quality when bidirectional printing is conducted without regulating a head gap after a head unit is replaced in an ink jet printer of the type in which the whole head unit is replaced by integrating a print head with an ink tank as the head unit. CONSTITUTION: A printer 1 has a print head 21 of the ink jet type to be integrally replaced with an ink tank. The printer 1 stores the history of whether the head gap regulation is conducted or not as a gap regulation flag thereafter each time the head 21 is replaced. When the execution of bidirectional printing is requested, the flat is referred, and if the regulation is not yet conducted, the execution of the bidirectional printing is denied, and a unidirectional printing is forcibly executed. Further, at this time, a message for expediting to conduct the regulation is displayed on the liquid crystal display of the printer 1 or the display of a host machine 31.
