Try saving Printer.Printers to a file where you can load the file into an editor and look at the names carefully.
The next thing is to look at how you are saving the printer name. I assume you are using an INI file. IndexOf will only return an index on an exact match. So if there are trailing spaces in one but not the other, it is no match, even though they look identical.

I did what you suggested and the Listbox line looks the same as my Lblprinter variable. Here is how I load the listbox: For I := 0 to Printer.printers.Count -1 do LBxPrinters.Items.Add(Printer.printers[I]); I am wondering if it would be safer to save the Index number but my concern is that if the user adds a printer to the list then the index will be goofed up.

Try outputing the list from Printer.Printers to the lines of a Memo, or any other way where you can see them. I think you'll find that the name of the printer om Printer.Printers is a little different than the name that is shown in the common controls printer dialog. If you want to select the printer from a stored printer name, you need to make sure you store the name contained in Printer.Printers, not the printer dialog. This is easy to do. You can have the user select the printer from the printer dialog, but then save the name from Printer.Printers corresponding to the selected printer after they have selected it.
