ABSTRACT:
A recording apparatus is disclosed that, in use, is connected with a host apparatus, receives recording information from the host apparatus by direct memory access ("DMA") and can print received recording information by using a recording head. A first memory access circuit receives recording information from the host apparatus by DMA. A second memory access circuit supplies received recording information to the recording head with a timing appropriate for recording, using DMA. A priority circuit controls the respective priorities assigned to various types of DMA to ensure that all types of DMA demands can be accommodated within an acceptable length of time.
