However, it shows that it failed to connect with CUPS. udev-configure-printer[5761]: failed to connect to CUPS server; giving up I have provide the results to my printer checks below. Appreciate help to reestablish the proper connection of my printer and get it working with Ubuntu 16.04. tail -f /var/log/syslog Feb 2 22:36:38 Eliot kernel: [95807.581378] usb 1-14: New USB device found, idVendor=04a9, idProduct=1754 Feb 2 22:36:38 Eliot kernel: [95807.581387] usb 1-14: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Feb 2 22:36:38 Eliot kernel: [95807.581391] usb 1-14: Product: MG5300 series Feb 2 22:36:38 Eliot kernel: [95807.581395] usb 1-14: Manufacturer: Canon Feb 2 22:36:38 Eliot kernel: [95807.581399] usb 1-14: SerialNumber: 20EE62 Feb 2 22:36:38 Eliot kernel: [95807.591385] usblp 1-14:1.1: usblp0: USB Bidirectional printer dev 42 if 1 alt 0 proto 2 vid 0x04A9 pid 0x1754 Feb 2 22:36:38 Eliot kernel: [95807.591527] usb-storage 1-14:1.2: USB Mass Storage device detected Feb 2 22:36:38 Eliot kernel: [95807.593328] scsi host13: usb-storage 1-14:1.2 Feb 2 22:36:38 Eliot systemd[1]: Starting Automatic USB/Bluetooth printer setup (-devices-pci0000:00-0000:00:14.0-usb1-1\x2d14)...
