HP LaserJet P3005n toner
Your LaserJet P3005n takes the 51X (high yield) and 51A (standard yield). At our price that is about 0.4¢ a page.
The HP LaserJet P3005n is a mono laser printer in the LaserJet P3005 series, which shares cartridges across 5 models.
It takes two black cartridges that differ only in capacity: the 51A at about 6,500 pages and the 51X at about 13,000. At our prices that is 0.6¢ a page against 0.4¢, 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.
