Abstract
An ink-jet printer has an ink-jet printing unit for recording an image by attaching ink onto a recording medium in accordance with data, photo-sensors for determining whether the recording medium is an overhead projector film or a normal paper sheet by utilizing the difference in light-transmitting properties therebetween, and a central processing unit for controlling the density of the image recorded by the ink-jet printing unit in accordance with the determination result of the photo-sensors.

A recording apparatus comprising:
- recording means for recording an image by attaching dots of a recording material onto a recording medium in accordance with data;
- determining means for determining a type of the recording medium;
- and
- control means for controlling a density of the image recorded by said recording means in accordance with a determination result of said determining means in such a manner that a plurality of dots are attached onto a particular type of recording medium for individual pixels in the image and the plurality of dots are shifted by a predetermined amount to permit superposed printing.

A recording apparatus comprising:
- recording means for recording an image by scanning along a recording medium and ejecting ink droplets onto the recording medium;
- determining means for determining a type of the recording medium;
- and
- control means for controlling said recording means so as to perform a plurality of ink ejection operations to eject a plurality of droplets onto the recording medium for individual pixels in the image in such a manner that the plurality of droplets are shifted by a predetermined amount to permit superposed printing when said determining means determines that the recording medium is of a particular type.
