I am trying to modify the Print Setup option found under `File > Print Setup.`

I am using Windows Script Host with Python. I use the `Alt + F` followed by `S` to open the appropriate dialogue box: 

![Print Setup](https://i.stack.imgur.com/01RSI.png)

When I do those commands by hand, the Print Setup box is in focus, so I can press `F` to select "Print to File" then `{ENTER}` or `O` to accept the changes.

However, I neither `ALT+F` nor `F` is selecting the File option.

```
shell = win32com.client.Dispatch("WScript.Shell")
shell.AppActivate('Point of Sale')
shell.SendKeys("%fs") # I also tried "%fsf and "%fs%f" removing the other call to SendKeys"
time.sleep(0.1) # Removing this (or using a longer wait) makes no difference
shell.SendKeys("F") 

```
