I use this code with Delphi 2007:

for I := 0 to Pred(Printer.Printers.Count) do
  Listbox1.items.add(Printer.Printers[I]);

I have a customer that has a Xerox Phaser printer installed which is his 
default printer but it does not show in the list.
He is using Windows 7, 64bit.

Anyone have an idea as to why this might happen ?

Thanks
JT
