It seems to me that CLT-4072S is a multipack of 4 cartons whereas for CLT-P4072C the 4 toners are in one box, and cheaper. In fact the same cartridges. Note: Samsung printers are now HP.

Sorry, no idea, I don't know this xpress c460w.

Is it possible that this CLT-C4072-HC is from a different toner and not from the printer itself? I can't find anything under this name on this link: http://www.samsung.com/ch/consumer/computer-peripherals/printer-multifunction/

I recently bought the product and checked the packaging earlier. The CLX-3170FN model is not mentioned on it, which probably indicates that these toners do not fit. But I am not an expert.
