Before getting into the specific brands, you must understand first that using any compatible toner will effect your environment beneficially. It will greatly reduce waste and pollution as well as conserve resources. This is the best bet for one who is environmentally friendly.A great simplicity the Samsung ML-3471ND holds is its duplex button. Most laser printers will require the user to go through the settings through the LCD menu but Samsung make it much simpler, which is convenient as printing on both sides of a sheet is common and also an eco-friendly way to work. Now, Brother of course is a top brand for printers. Brother is especially a top brand for multifunctional printers. So the toners are going to have to match or exceed standards of their users. The machines focus on making the prints move quickly and in turn it is important to have a toner cartridge that is not going to clog or work slower than the machine. That would cause the prints to come out streaky and inadequate.A big issue in high volume printing is saving toner and therefore cutting costs. The Samsung ML-3471ND has another ingeniously simple button 'Toner Saver' which can save up to 40%. This gives users an option they may not always consider which can save a business a good amount of money. This is a feature exclusive to Samsung and should not be confused with a 'draft' mode which can leave text looking jagged and unfinished.
