They're using the term to apply to both ink and toner. I don't really want to be refilling toner tanks at home.

I had an Epson Ecotank ET-3000 series and was disappointed to find that the prints faded noticeably in just three month! I did a lot of research on ink permanence and got an ET-8550 and prints I made four years on that look pretty good.

Third party ink is trash though and there is no accountability. All the time I see on forums that somebody tried to make a borderless print and got an inksplosion and the common denominator is third party ink.
