Best Bang for the Buck

I have used two Okidata dot matrix printers since 1991. The first printer lasted over 21 years!. I've found that genuine OKI ribbons last at least twice as long as any other non-genuine ribbon I've tried. They may be a bit more expensive, but because they last so long, they're a lot cheaper.

Pros

Compatible with Microline 420, 421, 490, 491 (ML420, ML421, ML490, ML491)

Cons

Too long to wait
