4-Megabyte printer buffer

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.

Such a buffer is described here: it is Centronics-compatible, and ofters a memory size of 1 MByte or 4 Mbyte.
