magicolor 2 DeskLaser ports

[123321]

Just bought a magicolor 2 DeskLaser printer on ebay. On back of machine is a parallel port & two other port openings, one has TX above it & the other one has RX below it. Between the two ports is the word link. What is TX & RX and how do you hook them up to a network?

I have a laserjet 4m that I am trying to use with my mac G4 tower. What is the
best way to make this work? (parallel port to USB)
