PURPOSE: A method of liquid crystal printing is provided to achieve an enhanced speed and quality of printing with an improved resolution while electrically charging the printer roller to collect toner powder. CONSTITUTION: A method of liquid crystal printing comprises the steps of shielding or passing a light using a liquid crystal and partially and electrically neutralize a printer roller being charged by the artificial shielding or passing of light. An insulated plate is punched to have a line of micro holes, and a liquid crystalline is inserted into the hole and each hole is connected with electrode. A light source is installed on the liquid crystal and a roller having a photosemiconductor surface is arranged under the liquid crystal. When the light source emits light to reach the liquid crystal which shields or passes light according to whether a current is applied to the liquid crystal. Thus, the light is passing through the unprinting portion, and the passed light radiates the surface of the roller which becomes neutralized. Toner powder is applied as rotating the roller, then the toner powder will be adhered only to the light-shielded portion. Subsequently, the toner powder is transferred to a paper to be charged to positive.
