I was just wondering what you all think of it.... I have a $100 printer, and have to replace a $60 toner cartridge, but I don't want to buy a new one. I was thinking of just getting a kit to refill it, but here are my main concerns: 1. Will the quality still be ok? This is my main concern! 2. Will it ruin the printer in any way? 3. Will it void the warranty? (I mean I don't really care, but it'd be nice to know. Samsung is the brand.) Thanks!
