OK, I realize that I already posted this, but it won't let me delete or modify the old one, and there are some changes.
These small boxes made by HP have a parallel port and an ethernet port. What they do is allow you to make any printer with a parallel port availible to your whole network. These go on eBay for around 75 dollars, but because I have so many I'm going to say $50 plus shipping (which should be no more than $5). Included will be the JetDirect, power adapter, and software. These are compatible with Mac OS Classic, Mac OS X, and at least Windows 2000 and XP (probably more). The configuration software is Windows only.
Email me at email@example.com if you're interested.
I'll also accept as a trade a 4 or 5 port 10/100 ethernet router.
