Abstract: A dryer including an air condensing unit that can use cooling water to reduce air moisture by condensation in a non-contact manner. The air condensing unit includes a condensing duct and a hollow rib enclosed inside the condensing duct. During a drying process, cooling water flows through the hollow rib and, at the same time, air coming from the tub flows through the hollow rib and is cooled off by the cooling water. The cooled air exits the condensing duct and flows back to the tub after travelling through a drying duct that includes a heater. The external wall and/or internal wall of the rib has protrusions and depressions formed in a three-dimensional pattern to increase surface area.

Abstract: A method and apparatus for adjusting the size of an object included in a printing target to be printed according to a reduction ratio, the method including calculating at least one dimensional value of the object after the size of the object has been converted according to a reduction ratio, by the way of the at least one processor; and changing the at least one dimensional value to a predetermined value, when the calculated the at least one dimensional value is equal to or less than a reference dimensional value, by the way of the at least one processor.

Abstract: A print control terminal device, which is connected to an image forming apparatus, includes: a User Interface (UI) unit which receives a print command for a target document; a printer driver unit which detects a transparency region, which is a region to which transparency is applied, from the target document by analyzing one or more rendering commands for each object included in the target document, and generates print data by inserting transparency information into pixel data corresponding to the detected transparency region; and a communication interface unit which transmits the generated print data to the image forming apparatus.

Abstract: A method of controlling scaled-down (size-reduced) printing for a host device and the host device using the method, the method including inputting a scaling-down mode for the print document through a user interface (UI) of the host device; inputting a scaling-down rate fine adjustment for the scaling-down mode to generate a new scaling-down rate; and applying the new scaling-down rate to the print document. Thus, a user is provided with the convenience of obtaining a scaled-down print result that is not distorted.

Abstract: An apparatus and method of changing a printer driver, and a printing system and method using the same. The apparatus includes a buffer to store a print command, a driver storing unit to store a plurality of printer drivers corresponding to a designated printer, a driver selecting unit to select a printer driver corresponding to printer identification information from the driver storing unit when the printer identification information is input, and a command processing unit generate data that is used for printing by processing the print command stored in the buffer using the selected printer driver and generating an error signal if an error occurs during processing the print command.

Abstract: A method and apparatus for adjusting the size of an object included in a printing target to be printed according to a reduction ratio, the method including: calculating at least one of a width and height of the object; and when the calculated width or height of the object is 0, the object width or the object height is changed to a predetermined value, and the changed value is set. By doing so, when the printing target to be printed according to the reduction ratio is printed, a phenomenon in which the object does not appear on a print medium is prevented.

Abstract: A bitmap image conversion apparatus and a method for rotating a bitmap image are. The apparatus includes an edge information calculator to calculate information on an edge of a rotated bitmap corresponding to a predetermined edge of a source bitmap using bitmap information, a line information calculator to calculate line information to generate the rotated bitmap using the edge information of the rotated bitmap, and a bitmap generator to generate a final rotated bitmap using the edge information of the rotated bitmap and the line information. Accordingly, the calculation rate of bitmap image rotation can be enhanced.

Abstract: A printing method includes encapsulating gradation information about a gradation object for printing, transmitting the encapsulated gradation information to the rendering unit, generating a raster image by the rendering unit corresponding to the gradation object by using the encapsulated and transmitted gradation information, and performing a printing operation according to the generated raster image. Accordingly, since the rendering unit performs a rendering operation at once based on the encapsulated gradation information of the gradation object, the raster images are more rapidly generated and printed. Since it is not required to generate the tens of thousand or hundred of thousands of scan line commands to process the gradation object, memory is more effectively utilized.
