The bidirectional parallel interface offers the so called “nibble” mode of
the IEEE1284 interface norm. This enables installation in accordance
with Win 95 “Plug & Play”.
The standard parallel interface is able to transfer data at a speed of max.
30,000 bytes per second. When the receiving buffer is full, the data input
is blocked until the data buffer is empty. This guarantees data trans-
mission in blocks of 1 KB.
