Abstract
A printer which can perform color printing by using a plurality of color ink, and if some color ink is exhausted, prevents wasteful consumption of other color ink, and a facsimile apparatus, using the printer, which enables to confirm whether or not printing based on received facsimile image data using ink has been normally performed. In a case where printing is performed based on print data from an external computer, printhead 5 is moved to a position opposite to photosensor 8, and test ink discharge is performed with regard to all the plurality of color ink prior to print operation. If it is judged that even one of the plurality of color ink is exhausted, print operation is not performed. In case of printing based on facsimile reception image data, test ink discharge is performed after the print operation. If it is judged that ink is exhausted, received image data is stored into an image memory.
