<p>In a printer where rollers in a feeding section ensure the accuracy of sheet feeding, recording by the interlace method generally causes a non-printable area on the lower end of a printing medium, in which an image can not be recorded. In an ink jet printer (22) of the present invention, the interlace method is applied to record an image in a first area where the rollers (25a, 27a) in the feeding section ensure the accuracy of sheet feeding, in order to attain the high picture quality. A printable area where an image can be recorded is extended to a second area, where rollers (25a, 27a) in a delivering section are used to carry out the sheet feeding of relatively low accuracy after the lower end of the printing medium (P) comes off the rollers (25a) in the feeding section. The second are does not directly adjoin to the first area, but there is a middle area that adjoins to both the first area and the second area and enables image recording with sufficient accuracy of sheet feeding. The intermediate processing in the middle area with smaller amounts of sub-scan than the amounts of sub-scan in the first area effectively extends the high-quality image recording area that ensures recording of the image with the high quality equivalent to that in the first area. <IMAGE></p> |
