An image printing apparatus includes a print head for printing images. A microcontroller that includes a wafer substrate is provided. Processor circuitry is positioned on the wafer substrate. Print head interface circuitry is also positioned on the wafer substrate and is connected between the processor circuitry and the print head. The print head interface circuitry is configured to facilitate communication between the processor circuitry and the print head. Bus interface circuitry that is discrete from the print head interface circuitry is connected to the processor circuitry so that the processor circuitry can communicate with devices other than the print head via a bus.
L'invention concerne un appareil d'impression d'images comprenant une tête d'impression permettant d'imprimer des images, ainsi qu'une micro-unité de commande comprenant un substrat de plaquette. Un ensemble de circuits de processeur est positionné sur le substrat de plaquette. Un ensemble de circuits d'interface de la tête d'impression est également positionné sur le substrat de plaquette et est connecté entre l'ensemble de circuits du processeur et la tête d'impression. L'ensemble de circuits d'interface de la tête d'impression est conçu pour faciliter la communication entre l'ensemble de circuits du processeur et la tête d'impression. Un ensemble de circuits d'interface bus, qui est distinct de celui de la tête d'impression, est connecté à l'ensemble de circuits du processeur, de manière que celui-ci puisse communiquer avec d'autres dispositifs que la tête d'impression, via un bus.
