In a computer network consisting of at least one host computer and computer peripheral devices, such as scanners, fax machines, and printers, a user may use a hot key on the scanner to copy, scan, e-mail, and faxing etc. via the control of an application program. An auto-crop module implemented in the host computer can automatically crop the image of a scanned sheet. The cropped image is saved in the memory device. Before sending the cropped image to the computer peripheral devices, the computing module will compute the output format of the cropped image according to the resolution requirement and scaling factor of the associated computer peripheral device. The retained position will be also saved in the memory. In response to the user operation, the image of the scanned sheet with its retained position will be transmitted to the printer or facsimile machine via the control of the application program.
