Comments about Clover Data Products� R6070 Nylon Printer Ribbon for OKI� ML-520, 521, 590, 591; Black:
I thought we could save money using this ribbon but it was such poor quality it could not be used. The ribbon prints from light to dark to light again. As they say " you get what you pay for" but we didn't even get that.
Bottom Line No, I would not recommend this to a friend
