  • Many label printers (especially the older ones) use a proprietary text-based language, and accept plain vanilla text input via their serial port. They don’t use a printer driver as such. To use one of them you have to learn their command language (usually pretty simple) and write a text file describing what you want to print using that language, and upload the file to the printer.

    Start with the printer documentation and go from there.

    Newer printers need linux drivers. Support varies.






  • When faced with an issue, I classify it according to one or more of these “buckets”:

    Bucket #1: Not actually a problem at all (usually just unnecessary drama).

    Bucket #2: A genuine problem, but not my problem (none of my business).

    Bucket #3: A genuine problem, but I can’t do anything about it (it is not within my sphere of influence, or is beyond my capability to solve).

    Bucket #4: A real problem that I can do something about (basically everything that isn’t in one of the other buckets).

    If an issue may be categorized into buckets 1, 2, or 3, I don’t waste time or energy on it. If it’s in bucket 4, I get to work on it. I think this approach has saved me much stress.



  • Antennas achieve “gain” by sacrificing radiated power in some directions to favor others. For omnidirectional antennas, this means flattening the pattern: less radiated energy off the end, and more perpendicular to the antenna. If you are mobile it is possible to take this too far.

    In my experience, it is hard to beat a simple quarter wave ground plane or whip antenna in typical applications. It’s not hard to make one, but if you are buying one you shouldn’t need to spend much money on it.









  • I don’t know about “ethical”, but I have used a color laser printer (Brother L3270CDW) for a few years and it’s cheap to run and works fine for everything except photos.

    Photo printers seem to need inkjet tech, and ink is absurdly expensive and throwing away the whole printhead (HP) is just wasteful. I have an inkjet but don’t use it anymore. For the rare instances that require photo quality I take it to a service bureau.
