4-Megabyte printer buffer

Print files, whether they contain text, graphics or both, seem to become larger and larger as the programs that output them, and the printers that produce the 'hard copy', become smarter every day. That is all very well, but we do not want to see our ever so fast PC being held up bya simple task such as printing. The solution to this well-known bottleneck is to use a fast intermediate storage device with a large memory to capture the printer data supplied by the computer. Such a buffer is described here: it is Centronics-compatible, and ofters a memory size of 1 MByte or 4 Mbyte.
