Ink jet printer
First Claim
1. An ink jet printer comprising:
- recording means including a printer head for jetting ink droplets while moving in a direction perpendicular to the direction of conveyance of a recording medium having a dot image forming surface and a rear edge, thereby to form a dot image on said recording medium according to an input time;
further comprising a conveying mechanism, including a gate roller that performs an intermittent feed operation at a speed corresponding to a pixel density of a character or pattern recorded on the recording medium; and
a roller provided downstream of said recording means, said roller being operated after the rear edge of said recording medium passes through said conveying mechanism located upstream of said recording means, to convey said recording medium while in contact with the dot image forming surface of said recording medium, said roller being movable into and out of engagement with said recording medium.
