Only “bug” I have found with it that rarely I setup a printer and the next day I go to use it and the setup is gone. Set it up again and then it stays. Doesn’t happen every time but have noticed it twice.
I do like it though, nice features and flexible for other printers. The built-in calibration is killer.
I did a quick blip on it a while ago when I started using it.
I Will be honest though, it’s now the only one I use at home despite a couple of small issues.
