A print controller initiates printing of a print job by at least one print head array of a printing system. In response to determining that the at least one print head array should be serviced, the print controller determines whether the servicing of the at least one print head array will interrupt the print job. In response to determining that the servicing will not interrupt the print job, the print controller causes movement of the at least one print head array from a given position to a servicing station of the printing system. In response to determining that the servicing will interrupt the print job, the print controller performs other tasks.
