Lexmark X6570 <---- Does not work! Update: I bought the X6750 ink cartridge and tried to use it in my Dell 948. The cartridges do look identical, but the X6570 (No. 42 or 44) does NOT work in the Dell 948. Don't waste your money. I suspect Dell has rigged the cartridge in some way so that you must buy their ink exclusively for them to make a profit off the ink. This is very common. They sell the printer for $30 bucks and then charge $30 a pop for the ink which is extremely cheap for them to produce. Pure profit. It's a bait and switch game.

It is not so much the type of toner as it is in matching the size and shape of the cartridge. You will need to find the model number of your printer and then look up the product number (SKU) of the cartridge that fits. Quite possibly the cartridge that is currently in your printer has the number on it.
