Oh, njroadfan is correct. That was the one I was referring to.
However, I found my second disk, but no cable. It's called "Granny Smith Connection Parallel Print Disk" by Zap Logic Corporation. It's a 400K disk and I think pre-System 6 system files. It has drivers (I think) for:
Apple DMP
Apple ImageWriter
Star PowerType
Epson MX-100
Epson FX-80
Citoh F10
Brother HR
Comrex CR
IBM Quiet
IBM Wheel
Juki 6300
Olympio RO
Epson RX-80
Epson RX-100
Epson MX-80
Epson FX-100
Star Gemini
Qume
Generally speaking, if you're trying to print to any non-Apple laser printer, so long as it supports PostScript, you can print to it using a generic PostScript driver. However, it's unlikely the printer supports AppleTalk (otherwise it'd also likely have drivers) so you'll also have the issue of getting your Mac onto a TCP/IP network, which will require a network bridge that supports MacIP.
