An ink supply system of a printing device, particularly designed for printing wide-sized media or documents, includes a container, a delivery device and a closed-loop belt. The container has a longitudinal opening and is provided with ink chambers, and the belt is disposed onto the opening of the container. The delivery device includes an intermediate and tubes. The intermediate is connected to the belt and used to move the tubes along the opening. Each if the tubes has a sucking portion immersed in the corresponding ink and a discharge portion used to connect to the corresponding printhead. The belt is connected to and pulled by the delivery device, and the holes are used to position the sucking portions, respectively. When the delivery device is actuated, the tubes are synchronously moved with the delivery device and the belt. The tubes with capillary action can continuously absorb the inks stored in the container and output it through the printheads without pressure loss.
