We have been testing a non-OEM cartridge for our color laser printer, with excellent results so far.  Instead of a “remanufactured” cartridge which has been refilled, these are newly manufactured cartridges that work just like the factory ones.  The prices are great: we paid $59 for a cartridge that costs $133 for the factory brand. The site is www.suppliesguys.com. They have compatibles for HP and for Samsung and may have compatibles for other brands, but not for all brands.
