@clock @stman @50htz @vidak @theruran @forthy42 Another problem with #IR is also that it's suffering from extreme attenuation at the slightest moisture.

• Like how water filters our red first, so you can imagine that the slightest rain or fog will block it.

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.

• Because degraded throughput is better than no connectivity!

Using like Red, Orange, Yellow, Green, Blue, Purple, White...

• I don't expect you to copy the #IrDA spec - besides high-power invisible light is kinda dangerous for bystanders - but I merely referenced it as means to see how this was done in the past and if any of that is salvageable...

@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?

• Speaking of #IrDA, does anyone make decentpy fast Transcievers that can actually do more than USB 1.1 speeds and work on #Linux?

I only see two HP Deskjets with #IrDA sensors.

450ci
995c

As far as I'm concerned, that's a wrap for HP unless someone else can add to the list.

Oddly, I can't find a single Epson printer with an IrDA sensor. Did they not make a single one?

Moving on to Canon.
