Title: Interface for printer
Inventor: HIRAYAMA YOSHIHIKO
IPC: G06K15/00
Filed: 1988-07-19
Abstract: PURPOSE:To enable image data to be transferred at extremely high speed through only hardware and not through software by providing a parallel I/O IC and a buffer RAM for storing printing data with an address counter and a switching circuit for switching between a strobe signal and a busy signal, in a parallel interface. CONSTITUTION:When a received instruction is an instruction for printing image data, a CPU 5 sets a switching circuit 2 through an I/O 6. When switching is finished, a busy signal is canceled, and a host computer starts transferring data. A strobe signal from the host computer increments an address counter 7, and causes the data to be written into a buffer RAM 8. When an output from the counter 7 becomes equal to a predetermined value, a detecting circuit 9 sets the switching circuit 2. The data from the buffer RAM 8 is transferred to a head data-transferring circuit 11 by high-speed DMA transfer, through changing over a switch 10 and in synchronism with a clock signal from the circuit 11. Thus, a data bus 4 for the CPU 5 is not occupied exclusively, so that the CPU can continue a required processing.
