The trouble is that, for one dubious reason or another, a lot of modern laser printers will refuse to print without a complete set of cartridges that report that they contain sufficient toner. Whether the colour in question is actually required and whether enough toner is physically present do not seem to be relevant.

That is easily solvable - clog/duct-tape the exit nozzle or tamper with the cartridge test (a lot of the substitute cartridges already disable this)
