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.
