Abstract
A printing system has a recording head, an ink cartridge and a computer. The recording head has a nozzle. The ink cartridge sprays the ink from the nozzle to a paper in accordance with a printing procedure. The computer detects the remaining amount of ink in the ink cartridge. The computer detects whether the remaining amount of ink is less than or equal to a predetermined reference value. The computer calculates usage required for the printing procedure of the ink when the remaining amount is determined to be less than or equal to the reference value. The computer compares the detected remaining amount of the ink when the remaining amount of ink is determined to be less than or equal to the reference value with the calculated usage.
