Abstract: A printing device includes a print engine, and a controller. The print engine performs an index print to print a plurality of images on one or more sheets, the plurality of images corresponding to respective ones of a plurality of files stored in an external memory. The controller controls the print engine. The controller performs determining a type of each of the plurality of files stored in the external device. The controller converts each file, which is determined as a non-image file and includes a page description language, to an image file representing contents of the each file by interpreting the page description language included in the each file. The controller generates a print command for the index print by referring to each image file which is stored in the external memory and each image file generated in the converting.

Abstract: A first correction is executed on target image data representative of a target image when a ratio of a number of first type pixels relative to a number of a plurality of pixels in the target image data is determined to be greater than or equal to a prescribed value. A second correction is executed on the target image data when the ratio is determined to be smaller than the prescribed value.

The first correction corrects both of internal pixel values and external pixel values which are within and out of a second range that contains the color value of the background color. The second correction corrects the internal pixel values and does not correct the external pixel values.

Abstract: In an image processing device having an image processing unit, a first determination process determines whether each of the plurality of blocks is a single-color block, a non-single-color block, or a non-determinative block. Determination of the non-determinative block is made when neither a single block condition nor a non-single-block condition is met. A second determination process determines whether the non-determinative block is the single block or the non-single block based on a result of the first determination process with respect to a neighboring block neighboring the non-determinative block. The blank determination process determines whether the image is a blank image based on at least one of number of single color blocks determined in the first determination process or the second determination process and number of non-single-color blocks determined in the first determination process or the second determination process.
