Hi! Thanks for contributing to the community. I see that you would like to know if there is a way to enable the Duplex printing option on a Mac computer.
Sorry. Your Canon GX2020 is capable of duplex printing. However, it is limited by the print options available through the computer operating system. If you have a Windows computer, the duplex printing option is available. However, on a Mac, the AirPrint options do not include Duplex Printing.
If you need to check what options are available through AirPrint on a Mac computer, you can visit the following page of your printer's manual:
https://ij.manual.canon/ij/webmanual/PrinterDriver/M/GX2000%20series/CO/EN/PPG/dg-c_pc_basic.html
If you need to find out if Mac Support has a solution that allows you to select a Duplex (or Double-Sided) Print option in the AirPrint window, I recommend contacting them. Here is a link to their support page:
https://support.apple.com/mac
As an alternative, you can ask the Apple community to see if they can offer any recommendations. Here is a link to that page:

We can offer one work-around. There is a way that you can manually print on both sides of the page. Here are the steps:
- Open your document and select Print from the File menu.
- When the Print settings offered through AirPrint open, make sure that the selected printer is the Canon GX2000 series.
- Under Pages, click on the "Selection" option.
- Choose all of the odd number pages: Example: 1,3,5,7...
- Click on the PRINT button to print the odd numbered pages.
- When the document finishes printing, put the stack in reverse order (with page 1 at the bottom of the stack).
Note: If your document is 6 pages long, page 5 should be placed on the top of the stack, page 3 should be placed in the middle of the stack, and page 1 should be placed in the bottom of the stack.
- Turn the stack over so that the bottom side of the pages are facing up, and reload the stack into the paper cassette. Make sure that the leading edge of the paper is facing the inside of the printer when placing it into the cassette.
- Go back to the document on your computer screen and select the Print option from the File menu.
- When the Print settings offered through AirPrint open, make sure that the selected printer is the Canon GX2000 series.
- Under Pages, click on the "Selection" option.
- Choose all of the even number pages: Example: 2,4,6,8...
- Click on the PRINT button to print the even numbered pages.
When the printing is complete, you will find that page 2 would have printed in the back side of page 1, page 4 would have printed on the back side of page 3, and so on. You can reorder the stack so that page 1 is at the top.
If you will need to make multiple copies of that two-sided document, it would be easier to print the entire document as it is (single-sided). After that, you can use the printer's Copy feature to make multiple two-sided documents. For information on how you can use the printer to make copies, you can visit the following page:
https://ij.manual.canon/ij/webmanual/Manual/All/GX2000%20series/EN/UG/ug-043.html

Until Two-Sided or Duplex printing is an option available through AirPrint, this is the only work-around we can offer. I hope this information helps. Thanks again.
