Abstract

PURPOSE: A device and method for controlling an engine is provided to reduce a manufacturing prime cost by reducing a capacity of a RAM and a font ROM storing data to be printed and to perform an output as actual 600 DPI by mounting a 300 DPI controller in a 600 DPI engine. CONSTITUTION: A code of a character or a picture to be printed is inputted in a printer(1). After the code input stage is performed, the character or the picture is magnified using a 300 DPI controller as an engine control(2). After the magnifying stage is performed, it is judged whether a resolution enhancing function is selected by a user(3). If the user wishes to enhance a resolution, a position to be corrected is detected in an edge and the detected position is stored in a memory(4). After the storing stage is performed, it is judged whether a paper discharging command is inputted or not(5). If a paper discharging command is inputted, a light is scanned and a point is imprinted on a position to be corrected and a printing process is performed as a 600 DPI(6).

Description

Apparatus and Method for controlling print engine using controller comprising curve correct S / W}

The present invention relates to an engine control apparatus and method by a controller having a curve correction S / W. More specifically, a 300 DPI controller is mounted in a 600 DPI (Dot Per Inch) engine to provide a RAM or a font ( The present invention relates to an engine control apparatus and method by a controller with a built-in curve correction S / W for correcting a step of a curve generated by using a controller for 300 DPI and outputting the actual 600 DPI.

The 600 DPI engine is a printer engine that prints 600 dots per inch and 600 dots per inch. The 300 DPI controller controls the printer's engine to make 300 dots per inch. It means a controller that makes 300 dots per inch.

Therefore, when the controller for 300 DPI is installed in the 600 DPI engine, the printed character or picture is enlarged twice, and the dot (DOT) is printed at 300 DPI.

Conventional printers use a 600 DPI engine (not shown) with a controller for 600 DPI (not shown) or a 300 DPI controller for a 600 DPI engine or a 300 DPI engine to obtain 600 DPI printed output. We used a resolution enhancement technique to obtain a printed output at 600 * 600 or 600 * 300.

However, when the 600 DPI controller is used to obtain such a 600 DPI printed output, the size of the font ROM is also quadrupled due to the size of the font being four times larger, and the data to be printed. The RAM capacity to store the memory is more than 4 times larger than when using the 300 DPI controller, which increases the burden on the user due to the RAM expansion. When the 300 DPI controller is mounted, the image is enlarged 4 times to output 600 DPI. Since printing at 300 DPI, the output result is the same as 300 DPI, meaning that the use of the engine at 600 DPI is meaningless, and when the resolution enhancement technique is introduced to the 300 DPI engine, a separate hardware configuration is required.

Accordingly, an object of the present invention is to reduce the production cost by minimizing the capacity of RAM and font ROM in which data to be printed is stored in view of the conventional problems, and at the same time equipped with a controller for 300 DPI in a 600 DPI engine, The present invention provides an engine control apparatus and method by a controller with a curve correction S / W for outputting at 600 DPI.
