This is the little picture. Look at the big picture. A full complement of high capacity toner cartridges for a color laser printer costs $1200. This is within $50 of the price of a base Xerox Phaser 6700/N, a low-end production color printer. More than a decade ago, the price of inkjet printers dropped to a point where it was no longer economic to replace the ink cartridges that were bundled with the printer. Replace the printer, instead. Many users began to do just that. For them, inkjet printers became disposable "razors." Use them and then toss them.
We have now reached that point with laser and laser-like printers. Replacement toner cartridges cost as much as a new printer. Economics dictate that we buy a new laser printer instead of toner for the old printer.
