Which ink/toner does the HP LaserJet P2055dn use?

The HP LaserJet P2055dn dates from 2008 and takes CE505A toner, which our record lists at 2300 pages for $95.00, or 4.13 cents a page. There is a high yield version, the CE505X, rated at 6500 pages, roughly 2.83 times the standard. We hold no list price for it, so we are not going to quote a cost per page we cannot show the arithmetic for. If you are pricing one, divide whatever the seller wants by 6500 and compare it with the 4.13 cents above.

Age is this machine's advantage. HP has stated that dynamic security is not enabled by firmware on printers manufactured before 1 December 2016, and a 2008 model sits well clear of that line, with no dynamic security notice published against it. Compatible CE505A and CE505X toner is what most owners fit. We record that as undocumented rather than certain, because HP has never published a list of which LaserJets carry the feature and has said so itself. Our last check was 1 September 2026.

Machines of this age fail mechanically before they fail electronically. Faded print that a gentle rock of the cartridge cures for a page or two means toner is genuinely low. A grey haze across the whole sheet, or a mark that repeats at a fixed interval, points at the drum inside the cartridge instead, and on this design the drum is part of the toner unit, so a replacement fixes both at once. Paper that jams on the way in is usually a tired pickup roller rather than anything to do with ink.

One more thing the age of this machine implies. The P2055dn is the only printer in our catalogue that takes the CE505A or CE505X, and no new host has joined it since 2008, among the longest such gaps we track. Toner softens the problem, because powder keeps, and compatible makers carry on producing a number while people still buy it. Even so, eighteen years earns some care: buy from sellers whose stock turns over, and the discontinuation guide lower down covers how to judge when a family is genuinely winding down.
