What's a good printer for minimal usage ?

A few thoughts.  First.  How many amps is going through THAT inductor?  It looks like something electro boom would make.

LED Laser or Laser LED or both?  Always confuses me.

45A Plasma Cutter so around there maximum. I only have a block circuit diagram and need to do some more digging yet so I can read the Arc voltage safely into a CNC controller and not fry it or just buy a divider and KISS. Fairly likely they are doing that in the internal circuitry so a little reverse engineering is needed  :-/O

Brother called the cheaper model 3230CDW a "Colour wireless LED Laser printer" and "Electrophotographic LED Printer" in the manual while the one I brought comes with a Class 1 rating and they call it a 'Color Laser' and '.Electrophotographic Laser Printer' in the manual
 

The cheaper one gets a bit of a beat up in the reviews for colour rendition and is also a bit slower but short of stripping both that is about all I based my extra few $ spend on. Part of that thinking was heat is part of the process and Lasers are likely a better more accurate point source over an LED here helping out the colour thing but  :-//

Either laser or LED. Fundamentally the same thing: Xerographic printing, that is, dry toner printing using a photosensitive drum. The difference is how the image is projected onto the drum: using a laser that scans across, or using an array of LEDs. Both can produce excellent output, and I’d say that the print quality depends more on the quality of the implementation than on the illumination technology chosen. LED printers can be made a bit more compact, however, since there’s no need for a scanning mechanism and associated optical path.

LED printers fascinate me.  If it's a 600 dpi printer, you need over 5000 LEDs to image a typical row of A4.  Are they using an OLED module or just discrete LEDs in some kind of custom package?   Is the module small and scaled to fit the page with lenses, or is it the size of the page?   I wonder if you could 'burn in' your printer's elements by using certain LEDs more - and how long it would take before this effect could be noticed.

Early DLP projectors had a way of doubling resolution by 'shaking' the DLP chip up and down slightly, effectively creating an interlaced pattern.  Maybe vibrating the drum could achieve some kind of micro-resolution improvement.

The one I took apart many years ago had an integrated bar with the LED dies. Looks like they haven't really changed.
