That was an assumption on how it should work, but it was implemented differently.

We do not sort the array returned by getAllPrinterNames() in PrintServiceLookupProvider.refreshServices(), so I assume Windows returns the installed printers in the same order. Therefore I think sorting the array is not necessary in this case.
I do not know, if it is always has the same order then the fix look fine, if we unsure then probably we can tweak it and sort.

Best regards, Sergey.
