Ordering supplies from Samsung printer

[techunsavvy]

I am thinking of buying a printer which allows me to purchase supplies (toner cartridges) easily and I came across Samsung's pamphlet saying that many Samsung printers allow users to purchase supplies directly from the printer itself.

If any of you have this type of printer, it will be great if you can give me your opinion on the ease of use and whether you actually use it or go online and purchase through Amazon etc instead.

I am also considering HP printers since they have SureSupply which makes it easy to purchase supplies.

If you have alternative recommendations that will also be great!

Thanks so much!
