Image forming device having resolution compensation function and method thereof

Abstract

An image forming device having a resolution compensation function comprises a storage for storing scaling information and resolution information with respect to printing data, a controller for setting a resolution of scaled printing data to a specific resolution based on the scaling information, and a print engine for forming an image of the received printing data according to the resolution set by the controller. The image forming device (such as a printer, a facsimile machine, or a copier) minimizes the degradation of the image quality when scaling an image to be printed or copied. Furthermore, the degradation of the scaled image quality is reduced when the image forming device is directly connected to a USB compatible storage medium or an image capturing device such as a digital camera, or a digital camcorder, and the image forming device receives and prints an image from the connected storage medium or the image capturing device. The present invention is especially suitable for a printer (which is an image forming device), and can be used with a photo printer which is used to print photographs or images. Alternatively, it can be connected to a network so that a plurality of host computers can share the image forming device.
