Hmm, I know that the Personal Laserwriter NT had only a solitary serial/Appletalk connection, therefore that model is not a possible mate for a PC. But, the NTR may be a different case. I say may be because the PC user is going to require a parallel connection for the best possible operation and they are going to require drivers. If they don't have any drivers, then they are plain out of luck.
I would suggest selling it to a Mac user as that will be easiest for both you and the final user.
