Within the Find Printers dialog, if a user clicks the Find Now button, all available printers on the network are shown. The printers seem to appear in a somewhat random order though where I'd expect them to be sorted by name (or something) by default. What determines the default sort order?

If they are appearing randomly, it is likely sorted by which printer responds first to the request.
They appear randomly, but you may sort them alphabetically via the context menu. Anyway please watch out that you may do this ordering independently in menu view or in in explorer view.
