<p>In a device with two or more nozzles which are retained within a print head, and which are operated to carry out printing of a single item of printed material, a situation may occur in which, despite a given nozzle becoming unable to continue printing due to the occurrence of a malfunction, the other nozzles are fine. In such a case, particularly when the customer is printing a printed material that does not permit the conveyor line to be quickly halted, considerable printing wastage is produced, despite the presence of nozzles which are able to print, resulting in the problem that the product production schedule is affected. To solve the aforementioned problem, when printing by operating two or more nozzles, in the event that a given nozzle is unable to continue printing due to the occurrence of a malfunction, control is carried out in such a way that printed content that should have been printed by the nozzle that is unable to continue printing is printed by other, normal nozzles. Through the use of the present invention, printing can continue without quickly halting the conveyor line, even when a malfunction has occurred in a given nozzle.</p> |
