I have the following situation

I have an Ethernet only HP Printer which I need to connect to a parallel port PC. 

Could I use an External JetDirect card to connect my Ethernet printer to a Parallel port PC?

--UPDATE--
There is an Ethernet port on the PC but it's being used to connect to the Domain. So I can't unplug the PC's ethernet. The room which has the PC has only 1 Ethernet port so we can't connect 2 devices to the network simulataneously.

The Printer has an Ethernet port only so I can't connect it via Parallel port cable.

But if I can bridge the Ethernet port to Parallel port that would solve my problem.
