Nano-toner: What It Is, What Changes in 2026 and Why It Matters for SMBs

Nano-toner: what it is, what changes in 2026 and why it matters to SMEs and home users
In 2023, HP introduced TerraJet. In 2025, Canon accelerated with a new family of toner under 5 µm. The industry press talks of "nano-toner" and 12% reductions in consumption per page. But there are two different technologies with similar names and a key question for any UK SME: is it worth switching now, and can compatible cartridges keep up?
Nano-toner vs nanoimprint lithography: not the same thing
Before we dive in, a clarification to avoid confusion. If you've arrived here searching for "Canon nanoimprint," you're most likely researching semiconductor manufacturing, not printer consumables. They are two distinct technologies that share the "nano" prefix and the Canon brand, but the similarity ends there.
Nano-toner (or nano toner) is toner powder for home and office laser printers, with particles generally below 5 µm and surface coatings on a nanometric scale, such as amorphous silica, titanium dioxide, or iron oxide. It's what HP markets under the TerraJet brand and what Canon applies in its EA and S Toner families. It is the exclusive focus of this article.
Nanoimprint lithography (NIL) is a chip manufacturing system. Canon announced its FPA-1200NZ2C equipment in October 2023 and delivered it to the Texas Institute for Electronics in September 2024. The process transfers nanometric patterns onto silicon wafers by pressing a mould with the pattern, like a stamp. Micron has already adopted NIL to reduce the manufacturing cost of DRAM. It has nothing to do with printing an invoice.
Both technologies leverage control at the nanometre scale, but one helps you print a delivery note, and the other enables memory chip manufacturing. In what follows, "nano-toner" in lowercase and hyphenated is reserved for toner powder; for lithography, we use "nanoimprint" or "nanoimprint lithography".
What nano-toner is and why it has arrived now
The average size of a toner particle has been steadily decreasing for three decades. In the 90s, the industry worked with particles of 14 to 16 µm, obtained by air-jet milling. In the 2000s and 2010s, the average dropped to 5-7 µm with the arrival of chemically produced toner. The leap to less than 5 µm that the press calls "nano-toner" is the current frontier, and it arrives with three convergent drivers that explain why now.
The first driver is purely physical. At 600 dpi, which was the laser standard a decade ago, particles of about 5 µm are sufficient to reproduce a dot with sharpness. At 1,200 dpi, the density of current professional equipment, the threshold drops to 3 µm. Without smaller particles, the "true 1,200 dpi" marketing is just a number on the spec sheet: the printed dot cannot be finer than the grain of the powder that forms it.
The second driver is energy. The resin in modern CPT particles melts at lower temperatures than milled toners, reducing the consumption of the fuser (the heater is the component that consumes the most electricity in a laser printer). Canon reports up to 15% less TEC (Typical Electricity Consumption) in the imageRUNNER ADVANCE DX range compared to previous models, according to its corporate sustainability report.
The third driver is regulatory, and it's the one least mentioned in the press. The EU Directive 2024/2881 requires the measurement of ultrafine particles at urban "supersites" and lowers the annual PM2.5 limit from 25 µg/m³ to 10 µg/m³ by 2030. The transposition into UK law should be ready before 11 December 2026. In turn, the German Blue Angel RAL-UZ 219 certification requires less than 3.05 × 10¹¹ particles emitted in 10 minutes of printing for small equipment. Manufacturers who want to sell in Europe have a direct incentive to reformulate the powder.
Against this backdrop is the quote that has been echoing since January 2026: "HP and Canon led with nano-toner technology with particles under 5 µm, resulting in higher resolution and a 12% reduction in consumption per page." The phrase comes from the 2025 Year in Review by Toner Cartridge Depot, an American aftermarket distributor. It's a credible figure and consistent with what manufacturers say, but it's a third-party estimate, not an official figure published by HP or Canon. It's worth keeping this in mind.
How it works: particles, coatings and fusing
Nano-toner technology rests on three pillars. Two act on the particle itself; the third, on the chemistry of the resin that forms it. None are spectacular on their own, but combined they explain why modern powder performs better than that of ten years ago.
Pillar 1: smaller, more spherical particles
There are two industrial routes to manufacture toner. The classic one is air-jet milling: you start with a block of resin with pigment and wax, pulverise it, and sieve it. This produces irregular particles of 7 to 10 µm. The economic limit is around 7 µm, according to the technical summary by Explained Chemistry: going lower increases the energy cost disproportionately.
The second route is chemically produced toner (CPT), by suspension or emulsion polymerisation. Here, particles are built up from chemistry, not broken down from a block. The result is uniform spheres of 3 to 8 µm with an average around 5 µm, according to the CPT fundamentals documented by Galliford Consulting. Modern nano-toner is almost always CPT with shape control; the choice between smooth spherical and "potato" (gently angular) depends on the use case.
Pillar 2: nanometric coatings
External nanoparticles (external additives) are fixed onto the base particle to control the flow and electrical charge of the powder inside the printer. The main players are:
- Amorphous silica (SiO₂) manages flow and triboelectric charge. The industry reference is AEROSIL® by Evonik, according to their datasheet for toner.
- Titanium dioxide (TiO₂) nanometric, often silanised with KH570 for a layer of about 3.1 nm that acts as a charge control agent (ScienceDirect, 2012).
- Iron oxide, alumina, zinc oxide, cerium oxide and carbon black serve functions of pigment, conductivity, and photocatalytic protection (Pirela et al. 2015).
A surface analysis conducted in 2020 by Morimoto and colleagues quantified between 4% and 5% of particles smaller than 100 nm on the surface of toner with external additives, mainly composed of amorphous TiO₂ and SiO₂.
Pillar 3: low-temperature fusing
The base resin is reformulated to melt at a lower temperature and is mixed with micro-dispersed wax that improves adhesion to paper. The fuser works, for example, at 145°C instead of 180°C. HP claims up to 27% less energy when printing in its TerraJet range, according to the official press release of 29 March 2023. Canon puts the improvement at 15% TEC for its ADVANCE DX range. Both figures are official and signed by the respective manufacturers.
"The 'nano' in nano-toner is in the skin, not in the core. A 5 µm CPT particle with a nanometric coating prints better than a 7 µm milled particle without one."
Editorial synthesis based on CPT technical literature
HP TerraJet and Canon nano-toner: what they launched and what they promise
Time to get into the details. Two manufacturers, two similar stories, but communicated with different degrees of caution. Here we separate what each officially claims from what the industry press interprets.
HP TerraJet
HP introduced TerraJet on 29 March 2023 as "the most sustainable toner technology to date" in its official press release. It was introduced in the HP Color LaserJet 4200/4300 range for SMEs, in the Enterprise 5000/6000 models, and in the Enterprise X500/X600 for high volume. The reference cartridge is the HP 213X: black version with an approximate yield of 9,000 pages and yellow, magenta, and cyan versions of 6,000 pages each, according to the manufacturer's specifications.
HP's official claims are:
- Up to 27% less energy when printing.
- Up to 78% less plastic in the cartridge and packaging.
- 35% recycled plastic in Enterprise cartridges.
- Up to 20% more printable colours in the gamut.
- "Protective shell" around the particle and a low-melt formula.
What HP doesn't publish is just as relevant. The press release does not state the exact particle size, does not describe the coating chemistry, and the term "nano" does not appear in official materials. Saying "HP TerraJet is nano-toner" is an industry interpretation (The Recycler, Altech FZCO), not a literal statement from HP. The 27% and 78% figures are from the manufacturer and are the ones you should use if you need to cite verifiable data.
Canon: V, S, CS and EA Toner
Canon describes its toner family on the official Supplies Technology page with four types: V Toner (pulverised, 5.5 µm), S Toner (polymerised CPT), CS Toner, and EA Toner (Emulsion Aggregation, low-melt polymerised). The 5.5 µm V Toner is officially the finest in the brand's pulverised catalogue; the EA Toner is its most modern option.
In September 2025, Canon expanded the imageFORCE range with R-VCSEL laser technology and "new toner" that delivers solid blacks at 1,200 dpi and speeds of up to 105 ppm. In parallel, it announced five new lasers for home and small office. The official energy consumption figures for its ADVANCE DX range are 15% less TEC and double the yield per bottle by controlling particle shape.
The viral figure of "12% less consumption per page" attributed to nano-toner in 2025 does not come from Canon. It comes, again, from the 2025 Year in Review by Toner Cartridge Depot, which aggregated its own estimates. The figure is consistent with a modern CPT formulation but has no OEM signature.
Quick HP vs Canon comparison

| Use of the term "nano" | Does not use it | Does not use it | Industry marketing |
The honest reading: both manufacturers sell modern toner with very fine particles and a low melting point, but neither calls it "nano". The label is put on by the press and the aftermarket. The benefits are real; the word is just packaging.
Health and air quality: the PM2.5 debate
Here it is advisable to lower the volume. Neither alarmism nor complacency. Just data.
The starting point is uncomfortable: approximately 30% of laser printers analysed in scientific literature are classified as "high emitters" of ultrafine particles below 0.1 µm. The figure comes from the classic Environmental Science & Technology 2008 and has been replicated in the Printer Emissions project by QUT for over a decade.
Concentrations measured during printing range from 3,000 to 1,300,000 particles/cm³ depending on the model, with the highest comparable to those on a busy urban motorway (Pirela et al. 2015). The modal size of emitted particles is between 49 and 208 nm, with most below 100 nm. The chemical composition is a mix of silica, alumina, titania, iron oxide, zinc oxide, copper oxide, cerium oxide, and carbon black. The latter is classified by IARC as a possible human carcinogen (Group 2B).
Measurements in German offices documented that indoor air during working hours rose to 5 times the particle concentration of ambient air (Scheepers et al. 2011).
But the clinical evidence is mixed. Three independent works moderate the picture:
- Herr et al. 2017 exposed 52 subjects (healthy, asthmatic, and sensitive) to 100,000 particles/cm³ for 75 min in a crossover study. It found no clinically relevant changes in lung mechanics.
- Kitamura et al. 2016 followed 112 toner manufacturing workers between 2004 and 2013. No significant acute or chronic respiratory effects.
- Morimoto et al. 2020 exposed Wistar rats to toner with TiO₂ and SiO₂ additives for 24 months. Low toxicity, no tumorigenesis or fibrosis.
The debate remains open for two reasons. The first is populational: a meta-analysis on general PM2.5 published in 2024 associates a 14.2% increase in lung cancer risk for every 10 µg/m³ of exposure. The second is biological: nano-particles can deposit in the alveoli and cross into the bloodstream, which opens up questions that short-term studies cannot close.
European regulation is moving in that direction. The EU Directive 2024/2881 lowers the PM2.5 limit from 25 µg/m³ to 10 µg/m³ by 2030 and requires mandatory monitoring of ultrafine particles at urban supersites. The transposition into UK law should be completed before 11 December 2026. The German Blue Angel RAL-UZ 219 certification maintains its threshold of 3.05 × 10¹¹ particles in 10 min for small equipment.
Can compatible cartridges match nano-toner?
This is the section that most interests anyone buying consumables in the UK, and also the easiest to distort with hype. The honest answer is not yes or no: it's "not yet, and it depends".
State of the compatible art in April 2026
Most of the European aftermarket works with powders of 5 to 7 µm, often CPT, supplied by a small group of specialist manufacturers: Katun EMEA, Print-Rite, Static Control, Mitsubishi Chemical, and CM Technology of Kelkheim. These are small, modern particles, but they don't yet reach the "sub-5 µm with controlled nanometric coatings" level that HP TerraJet or Canon EA Toner manage in-house.
The industry trend is clear. Marconet's analysis of OEM vs compatible argues that "compatible toner manufacturers have invested heavily in R&D to match OEM standards," and the Toner Cartridge Depot 2025 report adds that modern compatibles "offer OEM-level performance with a price advantage." The direction is right; the speed is slower than marketing suggests.
Real barriers to compatible nano-toner
- Chemistry and IP. The recipes for external additives (silanised TiO₂, hydrophobic SiO₂) are patented by Canon, HP, Ricoh, and Konica Minolta. Reverse engineering is not enough when the patent covers the process, not just the product.
- Cost of CPT. Suspension or emulsion polymerisation requires plants with eight-figure investments. Most small European remanufacturers buy the powder from Asian suppliers and do not manufacture from the monomer.
- Firmware and chip. HP blocks non-original cartridges with Dynamic Security, a mechanism we explain in detail in our article on how HP firmware blocks cartridges. Even if the powder is impeccable, if the chip doesn't validate, the printer won't accept the cartridge. If you're running into that problem now, the specific guide on what to do when your printer doesn't recognise the compatible toner is the next step.
- Fusing and fuser. A low-melt powder requires matching the equipment's fuser. A generic toner fused at the wrong temperature produces offset, ghosting, and incomplete fusion. The thermal window is narrower than in conventional powder.
What already exists in the European compatible market
- CPT powders of 5.5 to 6.5 µm with basic silica coating. Visual performance close to OEM for standard text and office use.
- Remanufactured cartridges with ISO 9001 and ISO 14001 certification, with recycled powder mixed with virgin powder.
- UK brands positioned as "original equivalent" with an approximate saving of 40% compared to the brand-name cartridge.
What does not yet exist in mass-market compatibles
- Nanometric coating of silanised TiO₂ plus hydrophobic SiO₂ comparable to TerraJet or EA Toner.
- Melting point as low as the OEM equivalent. The thermal window of the compatible is wider, not as fine-tuned.
- Guarantee of meeting the 3.05 × 10¹¹ particles/10 min threshold of Blue Angel. Very few compatibles are directly Blue Angel certified.
When a salesperson promises you "compatible nano-toner" in April 2026, it's wise to ask for the technical data sheet and certifications. If there is no specific emissions certification or measured particle size, what you are being sold is a well-formulated, aggressively labelled modern compatible, not nano-toner sensu stricto. It's key to differentiate legitimate compatibles from counterfeits: consult counterfeit vs compatible cartridges before buying from dubious channels.

Environmental impact: less plastic vs more fine particles
Any honest environmental assessment of nano-toner has two columns. Ignoring one is just hype.
Pros
- 78% less plastic in TerraJet cartridge and packaging (official HP figure).
- Up to 27% less energy in printing, which translates to fewer kWh and lower indirect CO₂ emissions.
- Canon reports double the pages per bottle by controlling particle shape.
- 12% less toner consumed per page (figure from Toner Cartridge Depot, not OEM). Less hazardous solid waste per printed page.
Cons or pending answers
- Smaller particles have a higher probability of ultrafine emission. The study Particle Emissions from Laser Printers: Have They Decreased? shows that around 30% of analysed lasers are still high emitters even with modern formulations.
- Nanoparticles of TiO₂ and SiO₂ as external additives are substances that the EUON / ECHA monitors under the European registry of nanomaterials.
- Recycling cartridges with CPT powder is more complex: the powder is finer and disperses more easily when handled.
Let's imagine a conceptual comparison. Printing 1,000 pages with conventional toner requires two 250-page cartridges at 7 µm and a fuser working at 180°C. The same job with OEM nano-toner can be done with a single 500-page cartridge below 5 µm and a fuser at 145°C. You win on energy, plastic, and waste. You lose on the risk of ultrafine emissions if the printer doesn't have good filtration.
The decisive filter is certification. Blue Angel RAL-UZ 219 or Energy Star plus correct ventilation are the realistic safeguards. Not all nano-toners are equal and not all printers that accept nano-toner emit little. To supplement the environmental analysis, you can consult Epson EcoTank vs Canon MegaTank vs HP Smart Tank as a point of comparison with ink tanks.
Buyer's guide: does it matter to you in 2026?
Three scenarios. For each, a clear recommendation.
Home User
Less than 500 pages/month · Home or single-person office
The quality difference between nano and conventional is practically invisible at your volume. Don't change your equipment for it. Prioritise silence, automatic duplexing, and a quality compatible toner. If you print a lot in colour and little text, consider an ink tank before a laser.
SME or Self-Employed
500 to 5,000 pages/month · Agency, clinic, law firm
Here, OEM nano-toner does have a measurable ROI in energy, fewer cartridge changes, and consistent colour. But an OEM HP 213X costs 3 to 4 times as much as a certified compatible. The honest rule: if you print in colour and the gamut matters, TerraJet or Canon EA are worth it; if you print text, an ISO 9001 certified compatible is the best cost-quality ratio.
Office / SMB
+5,000 pages/month · Department or branch with multiple workstations
The decision moves to TCO and compliance. EU Directive 2024/2881 and Blue Angel are redefining what a "healthy office" is. OEM nano-toner for colour, a certified printer, adequate ventilation, and compatibles for black and white overflow. A well-managed mix, not OEM purism.
5-point checklist before deciding
- Is my current printer compatible with nano-toner cartridges? (ask the manufacturer or check how to know which toner your printer needs before migrating).
- Do I have adequate ventilation in the space where the printer is located?
- What is my real monthly volume? Does it justify the OEM surcharge or should I mix and match?
- Can I apply a mixed strategy: OEM nano for colour, certified compatible for black and white?
- Does my compatible supplier offer ISO 9001 / 14001 and, if possible, Blue Angel certification?

Frequently Asked Questions
What exactly is nano-toner and how is it different from normal toner?
Nano-toner is toner powder with particles generally smaller than 5 µm, manufactured by chemical polymerisation (CPT) and coated on its surface with nanoparticles of amorphous silica, TiO₂, or iron oxide. Compared to conventional milled toner (7-10 µm, irregular shape), nano-toner offers higher true resolution at 1,200 dpi, more vivid colours, lower energy consumption in fusing, and less waste per page. Its "nano" comes from the surface coating, not the overall particle size. Source: Canon Supplies Technology and Evonik AEROSIL datasheet.
Are there compatible nano-toner cartridges for my HP or Canon in the UK?
In April 2026, not on a massive scale. Major aftermarket manufacturers (Katun, Print-Rite, Static Control, CM Technology) are developing powders close to 5-6 µm with basic coatings, but reproducing the exact recipe of HP TerraJet or Canon EA Toner is blocked by patents. A quality European compatible matches conventional 7-10 µm OEM toner, not the latest generation nano-toner. The first "nano" compatibles expected in the UK will likely arrive between 2027 and 2028. In the meantime, our range of compatible HP toner covers the modern standard with ISO certification.
Is it dangerous to my health to breathe near a laser printer using nano-toner?
Clinical evidence does not confirm significant harm from short exposures, even at high levels of 100,000 particles/cm³ (Herr et al. 2017). However, around 30% of laser printers are "high emitters" of ultrafine particles and carbon black is classified as a possible Group 2B carcinogen by the IARC. A prudent recommendation: ventilate the space, move the printer away from the workstation, and if you have asthma or allergies, choose models with Blue Angel RAL-UZ 219 certification.
How much energy and money do I really save with a nano-toner cartridge like HP TerraJet?
HP claims up to 27% less energy when printing and 78% less plastic in the cartridge and packaging (HP press release, 2023). In real cost per page for a typical UK SME, the operational saving is in the order of 5 to 10% annually on the printer's electricity bill plus waste reduction. The initial surcharge for an OEM cartridge versus a certified compatible usually absorbs that saving except in high-volume offices with an expensive electricity contract. You can find the full breakdown in the real cost of printing.
Is nano-toner the same as Canon's nanoimprint lithography?
No. Nanoimprint lithography is a semiconductor manufacturing technology. Canon launched the FPA-1200NZ2C equipment in 2023 and Micron has adopted it to manufacture DRAM. It transfers nanometric patterns to silicon wafers using a stamping mould. Nano-toner is powder for office and consumer laser printers. They share an etymological root ("control at the nanometric scale") and manufacturer (Canon), but they are completely different products and markets.
