Unless it has the brand name and product number, it is called "compatible" or "generic" toner.
There are MANY manufacturers--some are good, some are not.
So, if you don't want to do it twice, buy the stuff made by the company that made your printer.
On the other hand, I have had excellent "generics" and crappy "generics", some cost less than a quarter of the "Original Equipment Manufacturer" (OEM)
I have also had crappy OEM--but they replaced it quickly without an argument.
Unfortunately these days, you may get good, or bad, from any source.
