Comments about Okidata Printer Ribbon for Microline 520 & 521:
We use this ribbon on our work-horse printer. We run all our large in-house reports using it. It lasts and is very easy to install. I have been using these ribbons for over ten years and have only had one that did not work in all that time.

The plastic case pops open as the ribbon is moving through it's process of being stuffed back into the chamber. Quite frustrating as these are not inexpensive and sometimes happens with a brand new ribbon.
