How to set up Canon MF247 dw printer on Ubuntu 16.04

1. Go to https://www.usa.canon.com/internet/portal/us/home/support/details/printers/black-and-white-laser/imageclass-mf247dw?tab=drivers_downloads and download the Linux driver.
2. Manually install "sudo apt install libgcrypt20-dev"
3. Run sudo ./install.sh. (I had to edit the file and make sure it runs DEB instead of RPM by changing "if which rpm > /dev/null 2>&1;" to  if [ 1 -eq 0];

NOTE: I got this error:
#----------------------------------------------------#
# cups restart
#----------------------------------------------------#
/etc/init.d/cups restart
[ ok ] Restarting cups (via systemctl): cups.service.


Could not install.

But it seems this error doesn't matter.

4. Then I can add the printer by using its ip: 10.1.30.154
