Auto Polling
Both the serial port and parallel port of this printer can be
activated at the same time, i.e the printer can simultaneously
communicate with two PCs via different ports. However as no port
contention is made for this printer, if both PCs transmit data at the
same time the data may become damaged in the receiving buffer.
