Although these are just averages and may not seem all that different, in general if you are printing documents, it will probably cost you twice as much to run an inkjet printer than a laser printer. It is better to think of things in the long term when it comes to laser printers, because only then will you truly appreciate their value. If you buy a laser printer and then a backup toner cartridge at the same time, by the time you will have finished that second cartridge, you would have gone through roughly 10 inkjet cartridges.
So if you aren’t into printing color, then you are probably better off going with a laser printer over a standard inkjet printer. You will appreciate the speed and low maintenance of a laser printer, while also saving money on printer ink in the long run.
