The toner cartridge "Clt-K404s (BK)" is compatible for Samsung printers of the Xpress series, including models such as SL-C430W, SL-C480, SL-C480FN, SL-C480FW, SL-C480W and SL-C483W. It is therefore also suitable for a Samsung C48x printer, as these models are included in the list of compatible printers.

However, it is important to note that the manufacturer's reference to "HP Inc." may be an oversight, as the toner cartridge was developed specifically for Samsung printers.
