  • I myself prefer inkjet. Mainly because I don’t really understand the laser printer operation, I can’t even name all the rollers, but the simplicity of pouring more ink into old cartridges and easy head replacement (built into cartridges in my case) is nice, as well as compactness when requiring color. Maybe when I’ll once decide to study it I’ll try a laser.

    HP PSC 1315, somewhere around 20 years old. It has an absolutely botched USB replacement that’s not even fully inserted, but it’s somehow worked for years now.
    It was my first soldering attempt. You’ll squirm now, I didn’t know what flux was. I thought there wasn’t enough heat and went to MAXIMUM. 520°C (968°F) cooked contacts. But somehow it works…

    Hear me out, printers are relatively high-maintenance technology. I want some decent understanding to be able to deal with various faults first, but I am too lazy to study laser printers, so I use inkjet.

    But actually, I kinda want a… dot matrix. 24-pin for sure, but hear me out, I want a slow one. I want to watch it and listen to it printing, so I want it to take enough time. I am not joking. Many times I used high DPI printing which takes 20 minutes per page (A4) and I was watching the heads the entire time.


















  • Bluetooth has fairly low bitrate which also helps save power. The throughput will also vary with signal quality. It needs to somehow adjust to worse conditions, otherwise it will just keep cutting out. Streaming CD quality FLAC could probably be done over Bluetooth 5 2M PHY, but 2Mbps is just the physical layer. There’s also some overhead. Perhaps just enough would be left, but the bitrate will also vary with the content. Not everything can be compressed much, while some audio can be compressed quite a bit.

    Probably would work, but the reliability is also a question.

    Anyway, just guessing. Perhaps the 3Mbps EDR could be used just fine.

    Oh, Bluetooth 3.0 + HS could do 24Mbps. Sort of. It used WiFi to do that.
