Im not able to turn on double side printing! how to turn on? Please help me out.

In the pull down menu where you have selected "Layout," instead select "Printer Features." Then explore the different additional menus inside Printer Features, some of which SCROLL down even though that scrolling down aspect may not be obvious (some of them show only several lines of options but there are many more visible when you SCROLL down further). Then you will eventually see "Duplex Printing" or something like that which can be turned on or off. That is where you can get duplex printing, not from the "two-sided" menu that you show in your screen shot. It is not totally logical, I agree, but that is how to get duplex printing with many of the Canon printers.

Here are some screenshots, your specific submenu may show something different from mine, in mine I can turn duplex printing on/off via a submenu called "General 2" (there is also General 1, General 3 ... through General 5, but yours may be a bit different, but duplex is in there)

Two Things Come to Mind:

A. Restart Between Reinstalls:

If you reinstall drivers, then perform the following:

1. Uninstall: The Drivers
2. Restart: The Mac
3. Install: The Drivers
4. Restart: The Mac
5. Try this once more

And...

B. Resetting the Printing System:

One thing to mention is that I had the same issue with my Epson Eco Tank Printer - Reseting the Printing System fixed it, as the drivers were installed in an instant.

What to do:

1. Go To: System Preferences
2. Select: Printers & Scanners
3. Right-Click: on this pinter
4. Select: Reset printing system...
5. Click: Reset button

An additional thought: have you checked your user manual or their site to see if supports two sided printing on a Mac? Some printers may offer options on one platform, but not the other. I've had Canons for years and, from personal experience, if it is supported, it will show up as an option.

When you state that you installed the latest software from Canon's website, was it the drivers released in Oct 2020 for the 3000 series devices? Did you Reset the printing system to re-add these newly installed drivers so the device would use those?

In the pull down menu where you have selected "Layout," instead select "Printer Features."

Well, sorry, but not on my Canon - the two sided option is right at the top of the screenshot. There is nothing of significance in the pull down.

Contact Canon:

Having done some research, it appears there are multiple apps that you must uninstall. for the Canon Pixma G3000. But, there are also termorary files (caches) that must be removed. So, contact Canon using this information:

https://www.usa.canon.com/internet/portal/us/home/support/self-help-center/contact-us-by-phone

Screenshot:

Note: Calls might be a bit of a wait. And that makes sense because with COVID going around, many are at home working out of their houses, with more time on their hands to contact Canon Support. So, contact Canon, knowing that you might have to wait a few.

Yes different models have different options arranged differently in the print dialogue. I am hoping that the original poster's will work like mine does (mine is an older printer) because their dialogue box resembled mine and did not have the two-sided option box up front to check as yours does. It's something to try for if their dialogue lacks the option that yours shows.

Install the Correct Firmware:

You need the correct firmware to get this to work, on top of the drivers. Get it from the manufacturer (Canon), rather than a third-party device to avoid scams and junk from being installed.

So, Go Here and Chat with Canon Support: Canon Maintenance Service — Canon Support. Contacting support is the best way to go about troubleshooting the printer’s inoperability. So, perform a chat with the Manufacturer (Canon) using that link.
