HP LaserJet M234dw toner
Your LaserJet M234dw takes the 134A MICR (standard yield) and 134X MICR (high yield). At our price that is about 4.8¢ a page.
The HP LaserJet M234dw is a mono laser printer in the LaserJet M234 series, which shares cartridges across 1 models.
It takes two black cartridges that differ only in capacity: the 134A MICR at about 1,100 pages and the 134X MICR at about 2,400. At our prices that is 10¢ a page against 4.8¢, so the high-yield cartridge costs less to run unless you print very little.
On this printer the drum is built into the cartridge, so there is no separate drum to buy or reset. Every new cartridge brings a fresh drum with it.
When you compare prices, compare cost per page rather than the sticker price: a cheaper cartridge with half the rated yield costs more to run. Every cartridge here ships free, is covered by our printer damage protection and can be returned within 90 days, opened or not.
