ABSTRACT:
An image forming system includes: a computer for supplying image data; and a printer having a sub-tank for retaining ink to be supplied to a printing head and a system performing an on-demand supply of ink to the sub-tank. With the image forming system, during printing, the occurrence of a fuzzy image, due to ink in the sub-tank being exhausted, is prevented, and a reduction in the throughput of printing is also prevented. The computer counts, in advance, dots required for the printing of image data, and transmits the dot count, as well as image data, to the printer. The printer compares the amount of ink in the sub-tank with the required ink amount that based on the received dot counts. Only when it is determined that the remaining ink amount is insufficient, refilling of the sub-tank is performed, and thereafter, the printing of the image data is performed.
