I am not using common dialog. I able to display the printer devices in the combo box. Let say, I choose the printer A from combo box. How to show its printer preferences?I want to print as grayscale

Code:
'Add all the available printers to the combo box
        Combo7.Clear
        For i% = 0 To Printers.Count - 1
        
        Combo7.AddItem Printers(i%).DeviceName
        
        
        Next i%
       
       
       
       'Display the default printer
        For i% = 0 To Combo7.ListCount - 1
        If Combo7.List(i%) = Printer.DeviceName Then
        Combo7.ListIndex = i%
        Exit For
        End If
        Next i%
