Buying colour toner for laser printer.... Are the 3 different coloured toners sold separately?

I have decided to buy a Samsung CLP-315 Colour Laser Printer


Ive never owned a laser printer before.





When the COLOURED toner runs out, what do i do?


Is there just one toner called ';colour'; and I buy that one


OR


Are there 3 different coloured toners and i can buy them individually





So, say Magneta runs out, can I buy that separately??Buying colour toner for laser printer.... Are the 3 different coloured toners sold separately?
Toners for laser printers are ONLY sold in individual colors(Magenta,Cyan,Yellow and Black).
