Does anyone know the correct position on a Samsung ML2550DA toner
cartridge to put a hole in to empty the waste toner overflow?

I bought a refill kit for a Sansung ML1660 printer on eBay recently and
as well as the toner bottle and reset chip, the instructions included a
diagram showing where to drill the hole to empty the waste toner and a
small adhesive pad to close it up again. That might be your best bet.
