In an input buffer device for a printer using a first-in-first-out (FIFO) which can improve the data processing speed of a printer by receiving data from a host computer and processing the data by several bytes in a central processing unit (CPU) of the printer, and data input method, the input buffer device for a printer adopts an FIFO for generating an interrupt to the CPU for each input time of a predetermined byte unit of data, so that the performance of the CPU is improved by several times, the load of the CPU is prevented and the data processing speed is improved, thereby improving the overall system performance.
