Independent of the methods indicated here (screen capture + imagemagick conversion), there's the underlying question of E-innk hardware capabilities. I can speak to the latter. E-Ink screens are usually capable of a number of different refresh / display modes, which trade higher-quality visual appearance (crispness, greyscale, ghosting) for slower refresh. Refresh rates typically range from ~2-4 Hz at highest quality to 16--60 Hz at lower quality, but faster-updating modes. For most E-ink devices I've seen there are typically four modes, "Normal/Regal" (highest quality), "Speed", "A2", and "X-Mode" (fastest refresh). "Normal" is best for reading static text. "Speed" is sufficient for terminal-based sessions (I have Termux installed on my Onyx BOOX tablet), and most interactive apps (e.g., Web browsers, Podcast apps). I find little practical distinction between "Speed" and "A2". X-Mode does show considerale ghosting, but is indeed capable of video playback. Typically it's also possible to set the full-refresh interval (now many repaints are premitted between full refreshes which clear ghosting but give a distinct "flash" update. E-ink has a number of compromises, but is quite usable. Apps which are designed with its capabilities and limitations in mind are much better suited. Mostly that involves full-screen pagination of content rather than scrolling. Given the ubiquitous use of touch-based scrolling in most Mobile applications, this can be somewhat frustrating. I tend to use dedicated e-ink apps (such as Onyx's own NeoReader book reader), apps tuned for E-ink such as Einkbro, a Web browser, or terminal-based apps which work well in a text-based context.
