I had a Samsung CLP-315W that didn't work with original replacement toners that I kept in a cupboard for a couple of years, since I bought them during a sale.

I'm guessing that either one of their firmware updates broke their chip DRM recognition, or the chips that were in my original toners somehow corroded due to age.

Even for laser printers, it looks like it will be compatibles and refills for me moving forward.
