Best Printers That Don't Lock You Into OEM Ink (2026)

by Last Updated:

Last updated: September 25, 2026.

Quick answer: The printers least likely to lock you into manufacturer (OEM) ink in 2026 are Brother inkjets and lasers (such as the MFC-J1205W, MFC-J4335DW and HL-L2350DW), Canon PIXMA cartridge models (such as the TR4720), and ink tank printers like the Epson EcoTank ET-2800, which use refill bottles with no cartridge chips. Avoid any HP printer activated with HP+, which permanently accepts only Original HP ink.

The printer industry has a dirty secret: the hardware is often sold at a loss, with manufacturers planning to recover margin — and then some — through proprietary ink cartridges. A replacement ink set for some HP, Epson, and Canon printers can cost more than the printer itself. And in recent years, firmware updates have been weaponized to enforce that lock-in even more aggressively.

But you have options. Several excellent printers are designed — or simply happen — to work well with third-party ink. This guide ranks them by ink freedom, with Brother, Canon, and Epson EcoTank leading the way.

What "Ink Lock-In" Actually Means

Ink lock-in refers to any combination of hardware, software, or firmware that forces you to buy only the printer manufacturer's own ink. It includes:

  • Encrypted cartridge chips — the printer verifies a chip signature before allowing printing
  • Firmware updates — automatic updates that add or tighten chip verification checks
  • Subscription requirements — HP+ printers require enrollment in an ink subscription to unlock full features, and those features are disabled if you use non-HP ink
  • Yield throttling — some printers claim cartridges are empty before they actually are when non-OEM cartridges are installed

The printers below have been selected because they have little to none of this behavior.

Which Printers Let You Use Third-Party Ink? (At a Glance)

Printer Type Uses Best for
Brother MFC-J1205W Inkjet all-in-one LC401 / LC401XL Best overall inkjet
Brother MFC-J4335DW INKvestment Tank inkjet LC406 / LC406XL High-volume printing
Canon PIXMA TR4720 Inkjet all-in-one PG-245 / CL-246 Budget pick

Best Printers That Don't Lock You Into OEM Ink

1. Brother MFC-J1205W — Best Overall (Inkjet)

Brother consistently earns the top spot for ink freedom. The MFC-J1205W is a compact all-in-one with wireless printing, scanning, copying, and faxing. Brother does not use encrypted firmware to block third-party cartridges, and compatible LC401 ink is available at a fraction of OEM pricing. There are no subscription requirements, no HP+-style enrollment, and no firmware games.

2. Brother MFC-J4335DW — Best for High-Volume Printing

Brother's INKvestment Tank series is designed for users who print 500+ pages per month. The MFC-J4335DW comes loaded with enough ink for approximately one year of typical use, and uses LC406 and LC406XL cartridges, which are widely available from third-party suppliers. Brother's track record for third-party ink compatibility is unmatched in the inkjet market.

3. Canon PIXMA TR4720 — Best Budget Pick

Canon's PIXMA line has historically been one of the friendliest to third-party ink. The TR4720 uses PG-245/CL-246 cartridges, widely available in compatible form. Canon does not encrypt firmware in a way that blocks compatible cartridges — you may see an ink-level warning, but the printer will continue to print. No subscription required.

4. Canon PIXMA MG3620 — Best Entry-Level Canon

The MG3620 is an older but widely available Canon model that uses PG-245/CL-246 cartridges. It's a simple 2-cartridge all-in-one with wireless printing and scanning. Like the TR4720, it's permissive about third-party ink — you'll see warnings, but the printer will function. An excellent choice if you want a low-cost printer with cheap compatible ink.

5. Epson EcoTank ET-2800 — Best for Lowest Cost Per Page

Epson's EcoTank line sidesteps the cartridge model entirely — you fill large ink tanks from bottles rather than replacing small cartridges. The ET-2800 is the entry-level model, and replacement ink bottles yield thousands of pages at pennies per page. No subscriptions, no chip authentication. If you print regularly and want the absolute lowest per-page cost, this is the pick.

6. Brother HL-L2350DW — Best Laser Printer for Compatible Toner

If you primarily print text documents, a mono laser printer like the HL-L2350DW will beat any inkjet on cost per page. Brother's laser line is the gold standard for compatible toner compatibility — no firmware blocks, no chip encryption drama. The TN-760 high-yield compatible toner is widely available and yields thousands of pages.

Printers to Avoid

These printers are known for aggressive ink lock-in and should be avoided if you plan to use compatible cartridges:

  • Any HP printer requiring HP+ enrollment — HP+ locks you into genuine HP cartridges. Walk away.
  • HP ENVY 6000/6400 series — Uses HP 67 cartridges; firmware has repeatedly blocked compatible versions.
  • HP DeskJet 2700/4100 series — Entry-level HP printers with aggressive firmware update behavior.
  • Epson Expression Home XP-series (cartridge-based) — Unlike EcoTank, these can trigger ink recognition errors after firmware updates.

If you're currently using an HP printer and running into firmware issues, see our step-by-step guide: How to stop HP firmware updates from blocking your ink.

How to Evaluate Any Printer for Ink Freedom

Before buying any printer, ask these three questions:

  • Does it require a subscription? Any printer that requires enrollment in an ink subscription program (HP+, Canon PIXMA Print Plan, etc.) to unlock full features is a lock-in risk.
  • Does it auto-update firmware? If you can't disable automatic firmware updates, compatible ink cartridges may stop working after an update.
  • Are compatible cartridges widely available? Search for the cartridge model number + "compatible" and check how many reputable suppliers carry it. If the options are thin, the market has signaled something.

You can also use our Printer Ink Cost Calculator to compare the real cost of any printer — OEM vs. compatible ink side by side — before you buy. See our companion guide on which printers work best with compatible ink in 2026 for per-printer cost breakdowns.

Which Laser Printers Don't Use Chipped Toner Cartridges?

Brother's popular mono lasers that use the TN730/TN760 toner family (HL-L2350DW, HL-L2370DW, HL-L2390DW, MFC-L2710DW, MFC-L2750DW, DCP-L2550DW) rely on a mechanical reset gear rather than an authentication chip, which is why quality compatible toner works so reliably in them. The older TN630/TN660 family (HL-L2300D, MFC-L2700DW and similar) works the same way. Most current HP LaserJets use chipped cartridges, and many newer HP lasers are sold as HP+ models that accept only Original HP toner. Before buying any newer laser, check whether its toner is chipped and whether the model is subscription-locked.

Are There Printers That Don't Use Ink at All?

Yes. Laser printers use powdered toner instead of liquid ink. Thermal printers (shipping-label, barcode and receipt printers) use heat-sensitive labels or a ribbon and no ink cartridges; see our barcode and label printers. ZINK photo printers (small pocket printers) print on special paper with the color built in. For everyday documents and color printing, though, you'll need an inkjet, ink tank or laser printer.

What Type of Printer Doesn't Need Cartridges?

Ink tank printers (Epson EcoTank, Canon MegaTank, HP Smart Tank, Brother tank models) are filled from bottles instead of cartridges, and thermal printers need no ink at all. Epson's EcoTank bottles carry no chips, so third-party bottled ink works. Compare running costs in ink tank vs. cartridge printers.

What Is HP "Cartridge Protection" or Anti-Counterfeit, and Can I Turn It Off?

HP printers include features that check cartridge chips: "HP Cartridge Protection" ties cartridges to one printer, and "dynamic security" firmware can reject non-HP chips. On many models you can disable Cartridge Protection in the printer's Embedded Web Server or HP Smart settings and stop automatic firmware updates. You can't disable HP+ once it's activated. Step-by-step: how to stop HP firmware updates from blocking your ink, plus background on the 2026 HP firmware lawsuit.

Does Using Third-Party Ink Void Your Printer Warranty?

No. In the U.S., the Magnuson-Moss Warranty Act prevents manufacturers from voiding a warranty just because you used third-party cartridges. They can only refuse a repair they can prove the cartridge caused. See the actual legal answer.

Frequently Asked Questions

Which printer brand is best for third-party ink?

Brother, followed by Canon PIXMA cartridge models and ink tank printers from Epson and Canon. HP is the most restrictive, especially with HP+ and Instant Ink.

Can I turn off HP+?

No. HP+ is permanent once activated during setup. If you want to use remanufactured or compatible ink, decline HP+ when setting up a new HP printer.

Do Epson printers block third-party ink?

EcoTank bottles have no chips, so third-party ink works. Some Epson cartridge-based printers have rejected non-Epson cartridges after firmware updates, so keep automatic updates off on those models.

Do Canon printers block compatible cartridges?

Rarely. Canon PIXMA printers usually show a "non-genuine" or "ink level unknown" notice but keep printing.

What's the cheapest printer to run in 2026?

For color, an ink tank printer; for black text, a mono laser with compatible toner. See printers with the cheapest ink in 2026 and this month's CastleScore printer rankings.
