The Real Cost of Printing: Honest Math Per Page

Cost per page: the only metric that matters

Comparing cartridge prices on the shelf without looking at the declared page yield is like comparing cars by tank size while ignoring fuel use. Every serious cartridge, original or compatible, declares a page yield measured under ISO/IEC 19752 (monochrome laser) or ISO/IEC 19798 (colour laser), with 5% ink coverage on an A4 page.

The formula is trivial and free of tricks:

Cost per page = Cartridge price / ISO page yield

The most common mistake purchasing managers make is comparing the absolute cartridge price (49 EUR vs 24 EUR) when the original yields 1,600 pages and the compatible they looked at yields 800. Honest arithmetic requires matching yields: a 1,600-page compatible against a 1,600-page original. Only then is the cent per page a comparable figure.

Honest comparison at equivalent ISO yield

The table below pairs original and compatible cartridges with exactly the same declared ISO yield. Compatible prices correspond to the average retail price in the Startoner catalogue in April 2026; OEM prices correspond to the arithmetic mean of five authorised Spanish distributors consulted in the same month. All values include VAT.

Translated into real annual volumes, the cumulative impact is clearer than an isolated cent. Using the HP 85A as an example:

The middle row is the canonical example we use throughout this article: 4,893 pages a year is equivalent to an average household printing roughly 408 pages a month (school homework, invoices, occasional contracts). That household, on HP 85A originals, pays 241.71 EUR a year on toner. On the equivalent compatible it pays 73.40 EUR. The annual saving is 168.32 EUR and, accumulated over 3 years, comes to 504.96 EUR, almost 505 EUR on something printed exactly the same. That figure runs through the article as a reference because it is a real case, not an optimistic projection.

None of the figures above is a commercial promise: they are the arithmetic consequences of dividing price by declared ISO yield and multiplying by your volume. If your data are different, plug yours in. The method does not change.

Four printer families, four realities

Not every printer ages the same way in cost per page. Some architectures heavily penalise the original-buying user; others only moderately. Knowing the family of your machine lets you decide where to switch first. If you do not yet know which reference your printer uses, the guide how to know which toner your printer needs sorts that out in five minutes.

HP LaserJet Pro and LaserJet Enterprise

Home and small-office range where the OEM/compatible contrast is most aggressive: cartridges such as the 85A, 26A or 410A move from 4 to 5 c/pp on the original to 1.3 to 1.7 c/pp on certified compatible HP toner. It is the family where most small businesses concentrate their fleet and, therefore, where the absolute saving is largest.

Brother HL and DCP

Brother has historically kept a more reasonable OEM CPP (2.5 to 3 c/pp on cartridges such as the TN-2420 or TN-247) but there is still a 65 to 70% gap when moving to Brother compatible alternatives. These are ideal machines for users who prioritise mechanical reliability with controlled running costs.

Canon i-SENSYS

Architecture similar to the HP LaserJet Pro range (in fact, they share engines on several models). The 055 cartridge and the 070 family offer the largest optimisation margin when using references from the compatible Canon toner catalogue, especially in chipless versions that avoid firmware lockouts. For Pixma printers, see Canon ink cartridges.

Xerox WorkCentre and departmental copiers

In high-volume environments (10,000 to 50,000 pages/month), departmental copiers amortise the equipment cost quickly but amplify any extra cent per page. An OEM CPP of 4.20 c against 1.30 c compatible on a WorkCentre 3260 turns into 2,900 EUR of difference every 100,000 pages. See technical service and maintenance if your equipment needs support.

Inkjet: the Epson and Canon Pixma case

For inkjet the analysis changes: OEM cost per page is structurally higher (8 to 15 c/pp in colour at 20% coverage) because ink is sold in small cartridges. Compatible alternatives typically reduce cost by 60 to 75% while keeping office-grade quality. If you are moving to a continuous tank, the article Epson EcoTank vs Canon MegaTank vs HP Smart Tank compares the three big bets, and compatible Epson ink, compatible HP ink and compatible Brother ink cover the rest of the refills. The earlier dilemma between technologies is settled by ink cartridge or toner.

Three mechanisms that quietly inflate your bill

1. Standard cartridges vs high yield (XL)

The same cartridge often exists in two versions: standard and XL (or HC, high capacity). The XL version typically costs 40 to 60% more but delivers 2 to 3 times the yield. The XL cost per page is always lower than the standard one, but stores tend to feature the standard version on the shelf because the absolute price scares the casual buyer less. Always check both references before deciding.

2. Firmware updates that invalidate compatibles

Between 2016 and 2022, HP pushed firmware updates across multiple ranges so the printers would reject cartridges without an original chip. The practice, known as Dynamic Security, triggered the Italian 10 M EUR sanction (AGCM, December 2020), a class action in the United States that HP settled for 1.5 M USD in 2019 and a second class action in 2020. Since 2021, HP offers the option to disable Dynamic Security in the printer menus, although the default configuration usually ships with it on. Specific coverage in HP firmware blocks cartridges and a step-by-step fix in my printer does not recognise the compatible toner.

3. Default print mode and silent savings

Printers ship from the factory in high-quality mode. Switching to draft mode for internal documents cuts toner use by 30 to 50%. Setting duplex by default cuts paper use in half. Enabling greyscale for documents without corporate colour avoids drawing on the three CMY cartridges for pages that do not need them. Three free settings with compounding impact on real CPP, plus more techniques in how to extend the life of your cartridges.

Your real rights: UK and EU consumer law

A belief circulates among users, repeated to exhaustion: "if I use compatible cartridges I lose the printer warranty". It is false, and it is worth knowing exactly why, by citing the applicable rules. The full legal analysis of the differences between cartridge types is developed in counterfeit cartridges vs compatibles.

Consumer Rights Act 2015 and Directive (EU) 2019/771

The Consumer Rights Act 2015 in the United Kingdom, together with Directive (EU) 2019/771 transposed across EU member states, set a 3-year warranty of legal conformity from delivery for goods purchased from 1 January 2022 onwards. The seller is responsible for any lack of conformity and must offer remedies in order: repair, replacement, price reduction or termination of the contract.

British and European case law is clear: simply using a compatible consumable does not invalidate the equipment warranty. The manufacturer can only refuse the warranty if it conclusively proves that the specific consumable caused the claimed damage, and the burden of proof falls on the manufacturer, not on the buyer. It is a decisive legal nuance. More on how to exercise your return policy when a product does not arrive in conformity.

Directive 2011/83/EU, right of withdrawal

Directive 2011/83/EU on consumer rights, transposed across the United Kingdom and EU member states, recognises a 14 calendar-day withdrawal right with no need to justify it for distance and off-premises purchases. It applies to cartridges, toners and printers bought online, including those acquired from the Startoner catalogue and subject to our shipping terms.

Directive (EU) 2019/771, sale of goods

Directive (EU) 2019/771 on certain aspects concerning contracts for the sale of goods harmonises the warranty framework across the EU and reinforces the consumer position when the manufacturer tries to contractually limit the use of third-party consumables. Such clauses are, in many cases, unenforceable against the end consumer because they contradict mandatory rules.

Dynamic Security, art. 102 TFEU and antitrust fines

The Treaty on the Functioning of the European Union, in its article 102 TFEU, prohibits abuse of a dominant position in the internal market. National competition authorities, AGCM in Italy, CNMC in Spain, the Bundeskartellamt in Germany and the CMA in the United Kingdom, can investigate practices that, even when not explicitly illegal, restrict consumer freedom of choice over consumables.

The most relevant case to date is the Decision I842 of the Italian AGCM, December 2020, which fined Hewlett-Packard 10 million euros for imposing usage conditions and firmware updates that restricted interoperability with compatible consumables, without sufficient information to the buyer at the moment of purchase. The fine was confirmed by the Italian Consiglio di Stato in 2023.

In parallel, in November 2019 HP settled a class action in California (case Baker v. HP) by paying 1.5 million dollars for the same firmware pattern that blocked compatible cartridges without prior notice. A second class action, Mobile Emergency Housing Corp v. HP, was filed in 2020 and led to policy changes including the option to disable Dynamic Security. In the United Kingdom and Spain, regulators have looked into similar practices in other sectors (industrial dishwashers, maintenance contracts with parts exclusivity), so a domestic action specifically on printing consumables in the coming years cannot be ruled out.

None of these regulatory or judicial precedents appears on the box of a new printer. Knowing they exist is the first step to deciding with full information.

Two cases with auditable numbers

Saving models are easier to grasp with concrete profiles. Below, two cases representative of the average Startoner customer. The figures correspond to real 2025 invoices, anonymised and verified using the methodology described.

Neither profile changed printer. Both kept the manufacturer warranty (no hardware incident) and neither received complaints on print quality from external clients. Those are the two criteria that matter in the end: operational reliability and how the recipient perceives the result.

Action plan: audit your spend in 45 minutes

A minimum viable audit needs no external consultant or fleet management software. With the invoices from the last 12 months and a calculator you reach 80% of the diagnosis.

1. Step 1 (10 min). List every active printer and its exact model. Include home equipment if it is teleworking billed to the company. If you cannot identify your model, head to how to know which toner your printer needs.
2. Step 2 (10 min). Group cartridge purchases from the last 12 months from the invoices. Note reference, unit price and declared ISO yield.
3. Step 3 (10 min). Calculate your real current OEM CPP = total spent / total declared pages. Compare it with the compatible CPP from the comparison table for the same references.
4. Step 4 (10 min). Multiply the CPP difference by your observed annual volume. That is your realistic saving if you migrate to ISO 9001 certified compatibles without changing equipment. Cross-check with the calculator in this article.
5. Step 5 (5 min). Change the default print configuration: duplex on, draft mode for internal documents, greyscale when colour adds nothing. Additional 10 to 20% gain over CPP.

If the calculation yields an annual saving below 80 EUR, your fleet is probably already optimised or your volume is very low. If it exceeds 300 EUR, you have a clear business case to migrate at least partially to certified compatible consumables from our catalogue.
