When buying inks and toners for my printer you can fall on your face before, when you buy substandard Prrodukte. Unfortunately, the original toner and inks are usually - in contrast to the printers - very expensive. Fortunately offer professionals such as a pelican age Natie, when you get a Markenproduckt, but are not paying as much need as for the manufacturers product. I am very satisfied with the quality of Pelikan.
