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

by Last Updated:

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.

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 LC3033 super high-yield cartridges in compatible form. 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.
