VBA code to check whether a printer can print in duplex or not.

[kelly mort]

I have been on the Web reading about this topic for the past few days now but I have not achieved the right solution I am looking for.
I came across series of links of which one of them is:

https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.mrexcel.com/board/threads/add-duplex-command-to-print-button-vba.1039914/&ved=2ahUKEwjjwI_Zgu_xAhXVhVwKHeyeCOAQFjADegQILBAC&usg=AOvVaw0mrNRtjc-yjO58VqKiItW9

Which kind of instructed me to another link - a broken one:

https://support.microsoft.com/en-us/help/828638/how-to-set-duplex-printing-for-microsoft-word-automation-clients

Now this is exactly what I want to achieve:
1. I want to check if the active Printer can print in duplex or not.
2. If it can:
- is it possible to switch between duplex printing and non duplex printing?

I have tried to record macros to see if I could get the syntax but that's not showing me where to place the switch.

I understand others have mentioned APIs available for such task but I have not come across such APIs.

I wish someone could help me out with this.

Thanks in advance.
