Want to get some Toner for my new laser printer that has 4 refillable CMYK toner cartridges......can I use any make/brand of toner powder, are there proprietary differences from printer brand to brand?
your printer manual will state compatible power toner types and incompatible types.
I though that, but only states there own replacement cartridges, not toner refills.
Lots of people will refill toner or sell 3rd party toner. a lot of it is advertised as universal so just remember to check reviews and make sure its high quality you get what you pay for in toner.
