'Select Item' activity doesn't work for Excel Print Combo Box

‘Select Item’ activity doesn’t work for Excel Print Combo Box.
It is giving me the error: “Select item ‘combo box Which Printer’ : Attribute not supported by the current UiNode.”

It is able to detect the element and it is also able to click on that element. But if I use ‘Select Item’ activity after ‘clicking’ on the ‘Which Printer’ combo box, then this is the error it returns.

The same error occurred with my xerox printer. When I clicked on ‘select item’ after ‘Which printer’, an error occurred at that time. I tried to solve the problem but failed. Then I got the solution after searching many websites and contacted xerox printer repair in USA. Now my printer is working perfectly.
