Consider the interface between a computer and a printer. For a typical printout it is clearly impractical to send output data to the printer one byte or one word at a time (especially over a network!). In stead data to be printed is stored in a buffer at a known location in memory and transferred in blacks to memory in the printerA????1s memory.

            The printerA????1s memory is not always sufficient to hold the entire printout data at delays. Devise and describe, in as much detail as you can, an interrupt/DMA scheme that will assure that all documents will be successfully printed.
