I tried downloading other drivers for this Okidata2010 printer but they didn't work!! this was the only one that did, and it was the original manufacturer's disk. It's zipped up, but once extracted, double click on the "setup.exe" file and follow the instructions. It's better to have your printer on before you run the setup program.
I don't know whether it will work with other OS other than 95 or 98 but you can try! The setup program includes instructions on how to restore original configuration.
