Abstract
A printer has a print head check unit that performs an ink ejection check to confirm whether or not ink is being ejected normally from nozzles, the printer sets a flag F to 1 so as to start an ink ejection check and starts a paper feed process. When the processes has been terminated, the printer starts printing. Accordingly, ink ejection check takes place concurrently with the paper feed process, the overall time required for the processes can be reduced. In this way, the overall time required for the processes of the ejection check of the print recording liquid and an image forming process can be reduced. Further, the ink ejection check may be performed in parallel with or partly overlapping with a process of receiving print data, a process of conversion into print data, a process of ejecting paper after printing, or a flashing process.
