Both ports are present, and if two hosts are connected the first
host accessing it's respective port get's serviced.  If another job
come's in on the other port, it waits and will get printed when the
first ports finishes.  Of course this also means that if the sending
hosts don't have some way of "buffering" it's output,  the waiting
job could "hang" the secondary sending host, until the first job
finishes and the second (waiting job) starts and transmits successfully.

Some applications can misinterpret this "wait" to mean that the printer
is down, out of paper or plain non-existant.

Still, it's a nice standard feature and the print quality is wonderful.
You can also install up to 34MB of memory in this printer.  I'm not
sure if more memory might help free the ports faster or not.
