I'm more curious about why you hate printers.

I used to hate printers too but that changed when I started using HP Instant Ink. The printer needs to be connected to wifi all the time but on the flip side, the printer orders ink cartridges well in advance (so they get delivered in time and I have them ready when I need).

Might as well just buy a thermal printer.

I can also recommend drawing it instead of printing if you hate printers with the same passion as me. Record to beat for drawing a working QR code is 3 tries and I think about three hours (for an SSID of 13 bytes (5 unicode characters) and 19-character password). I did it mostly out of curiosity how hard it would actually be (spoiler: medium difficulty).

Thank you so much for the inspiration! I had a very relaxing time drawing my own as well, just now.

It is interesting how many ideas come to oneself when drawing and filling the grid. By the end I had all sorts of weird MC Escher style insanity.

> Your WiFi information is never sent to the server. This makes me think that we could use some flag that identifies purely static websites. Like next to the green https lock there is a sign that this website can not send data to any server

That would me amazing

This a great idea but it would be difficult to implement. Sure, it would be easy to catch (and block) HTTP requests other than OPTIONS and GET.

But even a GET request can be used to send data. Just pack the data you want to send in the query string and voila.

> hate printers with the same passion as me A remedy exists, it costs around 100€, is sold by Brother and is called "wifi-enabled laser printer". Your life will be free off printing woes onwards.

Can confirm. Zero problems in seven years. Though go for a model with wired Ethernet, still cheap and even more bulletproof.

So don’t allow GET with query params. You want the static moniker? It has to be static. No server interaction after load, and no sending any data during load.

You can still hide the data in "folders". /foo/bar/baz/buz can be totally dynamic on the server.

Had zero issues with wifi so far. I can even directly print from my iPhone. Being able to place the damn thing anywhere and hide it in a closet is great.
