The printer includes an input panel including a plurality of input keys, a controller for reading print type information sent through a communication interface together with print data and performing printing of a confidential print data file selected to be printed and received when a code that is the same as a secret code set in the received print type information is input through the input panel, and an engine controlled by the printer controller for printing an image corresponding to the print data to paper. According to the printer, the image printing system to which the printer is applied, and the method for printing the secret document, the printer performs printing only when the secret code input with respect to the confidential print data selected to be printed is the same as the previously set secret code. Accordingly, it is possible to prevent the confidential print matter from being exposed to others.

摘要： An apparatus and method for measuring a liquid level in a vessel using an acoustic wave. Acoustic tubes have first ends disposed vertically along a sidewall of the vessel for each of the liquid levels to be measured, and the tubes communicate with the inside of the vessel. Second ends of the tubes are connected to a common tube. A storage level sensor board generates the acoustic wave in the vessel, receives the acoustic wave propagated through the acoustic tubes and the common tube, and determines the level of liquid in the vessel based on the received acoustic wave.
