I think the options may be either:

An ecotank, the problem with them is that it doesnt respect the last point, since if it's not used in a while the ink it's going to dry and clog the print head, but i've seen some pretty good prints coming out of them+ on aliexpress you can get ink + other bits for cheap

A brother mfc, if i remember correctly there where color laser variants, the problem with them is cost and size, if i remember correctly they are office printers, space was not taken in cosideration when they where desined, so they are huge compared to standard printers + the ink cartriges are expensive, but last forever, i'm not sure if you can find cartiges on aliexpress, toner refills are more likely, but can be very messy and requiring cutting a hole in the cartriges, and i've found out that for the b/w toner printers it's the most economical way of getting ink for them

Sorry for the length of the comment.
