PaperTerm is an SSH terminal built for e-paper devices such as the Onyx Boox range, where screens redraw slowly and leave ghosting behind. It pairs the Termux terminal engine with a pure-Java SSH client, and adds the details that make a terminal usable on e-ink. It is a pure SSH client: there is no local shell and no local code execution. <b>Readable on e-paper</b> A dark-on-white ANSI palette keeps nvim, less and top legible instead of washing them out. Ghosting was stress-tested with fast streaming output, large dumps, full-screen inversion, repeated clears and TUI scrolling: the device's own EPD handling turned out to beat app-level refresh calls, which caused keyboard flashing, so PaperTerm deliberately stays out of the way. <b>Page turning, e-reader style</b> Turn pages with the volume keys or on-screen triangles. Auto, Page-keys and Wheel modes let editors and terminal multiplexers each behave the way they should. <b>Korean and CJK input</b> Composed syllables appear as they are finalized, without sending backspaces, so vim and other full-screen apps stay safe. Latin text is sent immediately. Jamo can optionally be shown while composing. <b>A keyboard row you control</b> The extra-keys row is fully customizable: a comma separates keys, a semicolon starts a new row, and KEY=label sets the icon. Any other token is typed literally, so symbols or whole words can become keys. <b>SSH essentials</b> Password and key authentication with a shared key store, known_hosts verification, keepalive, reconnect after an unexpected disconnect, clipboard support including OSC 52, and per-host environment injection so remote shells can switch to light themes. <b>Typography</b> Four bundled monospace fonts (CJK-capable by default), font import, and pinch-to-zoom sizing. PaperTerm is free software under the GPLv3.
