I don't see anything wrong with that guide.
I wouldn't recommend the rpi-update part though.
Are you sure that you waited long enough for the pi to boot again?
Depending on the pi and the sd card it can take some time to reboot.

The error just says that you default printer profile is missing.
Did you enter anything out of the ordinary in it when you edited it?
