How to print a list of items in a combobox to a printer

Question

In Visual Studio C# Winforms please help me understand how to print the list of items in a combobox and/or listbox.  I know a loop needs to be created to process through the list then output that list to a printer but so far I have not been able to make it work. I can print if I select one item from the list.  I cannot get the entire list to print to a printer.

Thanks in advance,
