We had a run-of-the-mill HP Deskjet back in the mid 90s which had an enormous cartridge that would last us, a family of two college professors in grad school and a daughter in elementary, a healthy 6 months. By the time it died in the early 2000s all the available ink-jet printers had cartridges a fraction of the size, and would last us just a week! So we opted for budget Samsung laser printers, and each toner cartridge took us back to 6 months of use. Toners aren't cheap, about 80% the cost of the printer. But at least we didn't have to worry about it running dry during finals week. We've since finished our PhD's, and our daughter finished her AB, so our printer is used much less. I haven't changed toners in a couple of years.
