@clock @stman @50htz @vidak @theruran @forthy42 Another problem with #IR is also that it's suffering from extreme attenuation at the slightest moisture.
Which is why I recommended to use multiple different visible light wavelenghts in parallel instead, so worst-case you got slow 10 Mbit/s blue-light only connectivity.
Using like Red, Orange, Yellow, Green, Blue, Purple, White...

@PurpleJillybeans This printer was fantastic. I believe I had the 5p. It ran great for years and then I foolishly gave it away in the mid-2000s.
Recently, I looked at buying another one because of the built-in #IrDA until I saw the eBay prices. Yikes!
Hopefully I can find one locally for a more reasonable price someday.
@paulrickards does it at least do #VFIR or #GigabitIR?

So far I have been looking at monochrome HP #LaserJet printers. I feel I have a fairly comprehensive list here.
Each of these are confirmed, by either looking at original manuals or pictures, to have an #IrDA sensor.
The dates, taken from various sources, are probably not exact and are used by me as reference only.
