I'm not sure what happened...But I changed the color cartridge in my printer and now I'm getting an error when I try to print? Something about usb stopped with status 81??

It will print with the old cartridge but not the new?

did you install it properly?

The cartridge?
I've had the printer for 4 years, I'd hope I'd install it properly! <lol>

Ok, it was a faulty printer cartridge. I contacted HP about it they suggested the cartridge might be bad. I exchanged it and it works fine now.
