According to the seller, it has a 4 pin mini din. From what I know, a 4 pin is for old Apple stuff, AKA the ADB port. I didn't know Lexmark manufactured peripherals for Apple, but who knows. Anyway, I bought one, and I'll see what I get.
There's also ADB to USB convertors, one of which I'll get if this is ADB.
Also first post here. Been lurking here for ages, love all the info!
