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.
I found this list of printers that these will work with:
"Virtually any HP or non-HP printer with a parallel port (except PPA or GDI printers, and HP Deskjet 710C, 712C, 720C, 722C, 820Cxi, 820Cse, 1000C, 1000CXI, 1000CSE printers, HP Original Photosmart printer (C3804A), "Host-based" or "Windows only" printers, HP LaserJet 3100 products, and HP Officejet PSC 500); Supports HP Officejet G series (full scanning and faxing), HP LaserJet 3150 (full scanning and faxing), HP LaserJet 1100A series (full scanning), HP Officejet Pro series and R series (basic scanning only), HP LaserJet printers, HP Deskjet printers, HP Designjet printers, HP 2000 and 2500 series printers, HP Business Inkjet 2200/2250 series, and HP Photosmart 1218 series"
