This is a most excellent place for technology news and articles.
This. I have a brother color laser printer I bought years ago. Literally before COVID happened, so I've had it about 6 years. I replaced the black stock toner, haven't replaced any others yet. Thing still prints like a champ even though it'll randomly forget Wi-Fi settings.... Lol
I bought an HP* color laser before Covid too. It's starting to bitch about cyan, but holy hell I abused the shit out of it during my studies and it's still good as new.
*I know, but their enterprise grade stuff is actually decent.
The only downside is up replaces the entire toner and drum cartridge. I prefer brother since they're separate. Drum is now expensive, but I doubt I'll ever use it enough to need a new drum lol.
