Patent attributes
A transport section transports a continuous printing paper in a predetermined transport direction. A first print section ejects first ink to the printing paper. A second print section is provided in a downstream side of the first print section in the transport direction, and ejects second ink to the printing paper. An ink amount estimating section estimates an amount of ink ejected to the printing paper from before printing by the first print section to before printing by the second print section, based on print data. A deviation amount obtaining section obtains a deviation amount between a print position by the first print section and a print position by the second print section at least based on the estimated ink amount. A print control section controls the print position by the second print section based on the deviation amount.
