How to set up your Canon Selphy CP900 wireless printing

Introduction
First, it's a bummer that Selphy Photo Print can only work with USB connection.

Second, Selphy CP900 is Wifi capable (good news), but I have no clue as how to set up a Wifi connection to print photos over Wifi to Selphy.

I tried to search for resources in Canon official sites, but to no avail. What is not cool is that the help page has no user input to grade and give comment about these help pages (thus prevent Canon from ever improving their help content). For that, I commend Microsoft for being better in that sense.

I switched to Google search for contribution by others about Selphy Wifi setup. I tried and fumbled with no luck until I tried the following steps.

Content

1. It seemed that Selphy only allowed installation of either USB connection OR Wifi connection. Canon doesn't allow installation of both USB and Wifi connections!
2. When I uninstalled my previous USB connected Selphy and reinstalled the Selphy Photo Print and its driver, it only allowed choosing either Wifi or USB. Reluctantly I chose Wifi and forsake USB connection.
3. One problem though, if I lose my internet connection (or communication with my router due to radio interference), will I be able to print or would I have to wait until I gain access to internet (or router) again?

Other matter

1. I wanted to find out if there is any other software besides Selphy Photo Print and I came upon Easy PhotoPrint Ex. It is like Selphy Photo Print but with more options. However, I can only use it to print on my other Canon printers BUT not Selphy.
2. The link for download of Easy Photo Print Ex is available here.
3. Selphy Wifi Ad hoc function seems to be useless with PCs and notebook running on earlier than Windows 8. I guess the ad hoc function is good for wifi cameras, camera phones and tablets?
4. Privacy. If you are as curious as me, you would have dismantled the ink cartridge after it is over. To my surprise, there is no ink but a roll of coloured films (e.g. blue, yellow, red, and white sections) inside the cartridge. Close examination of these coloured films over a light source revealed "printed photographs" still visible on the "ink" film (which is regarded as waste)! Well, I tried to salvage it to make art.
5. Laminated version. It would be great if next version of Selphy will incorporate lamination (matted) to the printed photograph. There is a requirement for matted passport photos and I couldn't use Selphy for printing. Wow, matted printing papers are expensive!

 All in all, I like Selphy and it will be very useful during travel (if the weight is not an issue and I can't wait to print photos of myself on vacation and mailing them to close relative and friends like postcards.
