Having supported enterprise laser printers at scale:

The low-end printers don't usually have repair parts and their operating costs are higher because their toner cartridges are small and relatively expensive.

This in contrast to the very large and initially-expensive laser printers: plenty of repair parts, fewer failures and cost per page is lower.

If you want the lowest TCO printer, the safest bet is a mid-high end model. For personal use, buy a used flagship laser printer 2-3 generations old.

People buy inkjet printers because their initial acquisition costs are low but they don't think about amortized cost per page.
