The printer is connected by USB. Thus its device URI is usb://Pantum/P2500W… and not whatever CUPS tries to sucker you into trying.
The Pantum drivers need to be installed using the root account, despite the ruse of the install script asking for a password if run from a user account.
I’m not sure that the thing can charge another device’s battery. That might have been the idea when it started out, but disappeared as things developed. I’ve set up a small tablet with the Sentio and DisplayLink stuff to get it to work with the Superbook. The best I can say about it is that it appeared to at least not drain the tablet battery – which is good, as it’s a limited tablet that discharges itself quite fast already. That it is also slow (rather nasty pointer lag) is unpleasant, but the idea of hauling it around with the Superbook hardware is nonsense anyway. The point was to have a phone-as-computer setup. This was merely a test.
I tried to use the Superbook as monitor on my main computer, but that requires DisplayLink. I’m running an older version of Linux Mint, and that on an older kernel (due to issues with a graphics card – yes, I just really need to upgrade to the newer Mint), so things didn’t work that way.
The laptop, however, is running the latest stable release. There, DisplayLink installed without (much) issue and after a few moments of goofy display began to run fairly well. It took a minor bit of fiddling. Really, I just needed to work out how the display driver controls worked. I had a dual-monitor (and dual keyboard) setup. The strange thing is that while the laptop has the larger screen, the Superbook has the higher resolution (1920×1080 instead of a mere 1366×768).
It’s just as well that I dislike trackpads. I suspect the Superbook trackpad is flaky at best and might be defunct. At least that means I won’t suffer “touch to mess up focus” with it.
At this point, I’m not sure what, if anything, I will eventually really use the Superbook for. It doesn’t work well with my current phone, which was the real point of the thing, and using it as an addition screen is a bit silly with a laptop, and rather pointless with my other computers. I suppose if I set up a Raspberry Pi for something, I could use it as the user interface – but I already have the main computer, the laptop, another setup for use whilst on treadmill, and there are a couple tablets about. So, for now, the Superbook is a “Great Idea… Almost.”
