What is the difference between toner and ink?
Toner is a dry plastic powder that a laser printer fuses onto paper with heat. Ink is a liquid that an inkjet sprays through microscopic nozzles. Toner cannot dry out and resists smudging; ink is cheaper per page in a refillable tank and is the only one of the two that prints photographs.
This question usually gets answered as a list of pros and cons, which obscures the fact that all of them come from one physical difference. Understand that difference and every practical consequence is predictable.
How we approached this
As an explanation first and a recommendation second, because the question is genuinely one about mechanism. Every claim below about durability, drying, text crispness and photographic output follows from how the two consumables physically reach the paper, and we have said which mechanism produces which consequence rather than asserting the consequence on its own.
The cost figures are ours, computed from supply prices and manufacturer-rated yields. The industry ranges for cartridge ink and color laser are cited to their publisher.
The mechanism
How toner gets onto paper
A laser charges a drum with a pattern of the page, the charged areas attract the toner powder, the powder transfers to the paper, and a hot fuser melts it so it bonds. The toner is a plastic powder throughout, and the result is a layer sitting on the paper surface.
How ink gets onto paper
An inkjet fires droplets of liquid ink through nozzles a fraction of a millimeter across. The ink then either soaks into the paper fibers (a dye ink) or dries on the surface (a pigment ink). Nothing is heated and nothing is fused.
The consequences, each traced to its cause
| Difference | Toner | Ink | Why |
|---|---|---|---|
| Can dry out | No | Yes | Powder has no solvent to evaporate; liquid ink at an unused nozzle dries and blocks it |
| Cost per page | ~3.3¢ | ~0.4¢ from a bottle | Toner is a manufactured powder in a cartridge; bottle ink has almost no packaging overhead |
| Color | Expensive, four cartridges | Cheap on a tank printer | Four separate toner cartridges versus four bottles of the same liquid |
| Photographs | No | Yes | Fused powder cannot produce the tonal depth of ink absorbed into a photo coating |
| Water and smudge resistance | Very good | Dye is poor; pigment is good | Fused toner is bonded plastic; dye ink is water-soluble in the fibers |
| Small text crispness | Crisp | Can spread slightly | Liquid can wick along paper fibers; fused powder cannot move |
| Speed | Fast | Modest | A laser images a whole page at once; an inkjet sweeps a head across it |
| Printer size | Bulkier | Compact | The fuser needs space and heat management |
Cost figures are our arithmetic on prices read 27 September 2026. Color laser pricing per Toner Buzz is between 12 and 15 cents a page.
“Is there a printer that does not use ink?”
This is a common way of asking the question, and the answer is: a laser printer, which uses toner powder rather than liquid ink. It still has a consumable — there is no printer that puts marks on ordinary paper without one — but nothing in it can dry out, which is usually what the person asking is actually worried about.
Thermal printers, which use heat-sensitive paper and no consumable at all, exist for receipts and labels. They cannot print a document and the output fades, so they are not an answer to this question.
The interesting middle case: pigment ink
Pigment ink blurs this comparison in a useful way. Like toner, it sits on the paper surface rather than soaking in, which gives it toner-like crispness on plain paper and toner-like resistance to smudging and water — while remaining a liquid ink with a liquid ink’s cost advantage.
What it does not inherit is toner’s immunity to drying, and it is slightly worse than dye ink on glossy photo paper for the same reason it is better on plain paper. The Canon MegaTank G3270 is the pigment-black printer we cover.
So which should you choose?
- Photographs or color? Ink, and specifically a refillable tank.
- Black text, printed rarely? Toner. The drying-out difference is the whole reason.
- Black text, printed constantly? Either; toner is faster, ink is cheaper.
- Documents that get handled or might get wet? Toner, or a pigment ink.
