A printing apparatus which can detect remaining ink with high precision regardless of trembles of ink surface in an ink tank caused by various factors such as scanning speed of a carriage, scanning width, impact of the carriage at the time of reversing the carriage scanning direction and the like, and can perform printing by efficiently utilizing the remaining ink, and a facsimile apparatus using the above printing apparatus. According to the apparatus, when a CPU controls print operation, the CPU dynamically changes the threshold value as a determination reference, utilized to detect remaining ink on the basis of an output current of a reflection type photosensor, in accordance with the scanning speed of carriage movement, the scanning width, and the stop period for reversing the scanning direction.
