What to verify before buying
- Whether the printer advertises IPP Everywhere/AirPrint to CUPS, or whether a vendor package is needed.
- Scanner support if you need all-in-one features.
- USB and local network printing without forced cloud setup.
- Whether the vendor publishes current Linux packages for your architecture.
Why the other three models are not Linux recommendations here
Brother's MFC-J4335DW U.S. page, the reviewed Epson ET-2850 user guide, and Canon's G3270 U.S. specification page do not provide the same explicit Linux compatibility evidence. Some may work through driverless protocols or separate regional packages, but protocol availability is not a substitute for verifying printing, scanning, maintenance, and the exact distribution. They remain in the general no-subscription guide, not this Linux recommendation.
Why this page belongs on the site
Linux-compatible printer searches overlap naturally with the no-lock-in audience: these users care about local control, repairability, open protocols, and predictable ownership.
