Review on ONLYU Compatible Cartridge Laserjet Printer by Jorge Bryant

Easy to install, print high-quality pages like genuine HP toner cartridges. I use it for my business (brochures and occasional flyers). MUST HACK: In order for these (or any) toner cartridges to work after the end of 2020, your HP printer must NOT be running the latest firmware. Updating the printer firmware (which by default is automatic unless you turn it off) effectively prevents all non-HP toners from working. to the version before HP blocked it. You'll have to do some web browsing to find out how this works for your particular model. Also, don't forget to disable "automatic firmware update" in your printer settings. IMHO this was a real BONEHEAD move by HP to get more dollars from its customers. Luckily, you can mitigate this with the hacks above.
