If you google "Kodak 8650 PS" (make sure to put the space in after the number) you'll get a hit for Kodak's site.
It's a discontinued printer, but there are drivers there for Windows 2000/XP. There are raster drivers and also Postscript drivers; I'd imagine you might have better luck with Postscript drivers because of the nature of that particular printing language.
If nothing else, you might be able to work out something so that you can print your images to Postscript files and download those to the printer, if it's got Postscript capabilities, that is. (Mind you, I don't know anything about your printer. Some printers simply had optional Postscript capabilities that came separate for a price.)
In any event, it looks like there are drivers for 2000/XP -- here's the link I found:
If you've already got these drivers, then it's simply a matter of using the Print Setup or Print function and choosing that printer, just as you would any other printer that you've installed on your system.
In other words, I don't know why you're trying the Export function.
One other thing: If your images are 16 bit and your printer will only accept 8-bit images for printing, you won't be able to choose that printer. You might want to try converting to 8-bit, with Image > Mode, before attempting to print again.
