[IPP] FYI - IPP exposure to open internet

[Kennedy, Smith (Wireless & IPP Standards)]

Do many printers implement the CUPS attributes?

It would be interesting to learn what motivated the owners to put their printers or print servers on public networks.

Cheers,
Smith

 Chris,

Thanks for forwarding this!

Looks like the bulk of the open "devices" are CUPS servers, which would have needed to be explicitly configured to allow remote access - the default is localhost-only, then local subnets (for regular printer sharing), then whole-internet (if you want things wide open...)
