The present invention provides a color cathode-ray tube that can attenuate vibration of an entire shadow mask positively with a simple structure. A user provided label is received at a second computational device. The structure for isolating devices includes a first isolation structure and a second isolation structure. Each of the ink-jet cartridges is detachably and independently embedded into one of the receiving cavities, and includes a body for storing ink, an ink-jet chip to be driven for ejecting the ink, a plurality of nozzles disposed on the ink-jet chip, and a control node for receiving signal to drive the ink-jet chip.
