For the most part, and while this is not always the case, They are incredibly expensive to use. The ink cartridges now cost almost as much as the printer, and you don’t get all that many pages before the cartridge runs out ink. Secondly, the cartridges have a bad tendency to dry out before you can use all of them up. Thirdly a lot of the older ones are not supported in the new O/S’s but the older lasers are. This is not always true though. I do have 4 inkjets sitting in storage because they are not supported, but only 1 very very old laser. I will also say that toner cartridges for lasers printers are not cheap either.
