I am quite annoyed after "breaking" two Inkjet printers in 5-6 years and want to buy a laser one this time, but am not sure how is the cartridge issue different between laser and inkjet. Do laser cartridges last longer? Is it less problematic to use non-original cartridges?
How well non-original cartridges work is highly dependent on the printer model. Some have more complex authentication of the cartridges and others it’s a simple page counter.
The main downside is color is a significant increase in cost of the printer as fairly expensive pieces need to be duplicated for each color.
