SOLVED: Ubuntu installation of Canon MX452 Inkjet Printer

Unlike many printers and Linux, this install went simply.

• Unbox printer.
• remove orange packing tape.
• unbox power cords and usb cable, install.
• open front pull-down cover, and one under it - push down on grey loops gently and put in inkjet cartridges.
• Put paper in at bottom, only hold 50 sheets or so.
• turn on, wait.
• open terminal window, type sudo ls and enter pw.
• open browser, get download from http://support-sg.canon-asia.com/contents/SG/EN/0100515301.html
• in terminal, cd ~/Downloads
• tar -xzvf cnijfilter*
• cnijfilter*
• On printer, turn off and on again just in case.
• sudo ./install.sh
• follow prompts accepting defaults.
• in browser, open google.com and print open page as test. Should hear printer working.

Done.
