ABSTRACT
In the early days of personal computers, most printers only could be connected using a serial interfaces. When printers started to have their own memory buffers, users found the serial link too slow. Manufacturers started offering printers with a parallel interface that could, in principle, receive data at least eight to ten times faster than was possible with the serial port. The adapter on the computer that allowed the user to connect to the parallel printer (i.e., the printer with a parallel input) was the parallel printer adapter.
