Smith, Very few - I am aware of a few office MFPs that use CUPS internally, and there are network print services that implement the CUPS-Get-Printers operation for AirPrint (to lookup a printer by its printer-id value - it is used for Bluetooth beacons), but the numbers of devices and spread of version numbers sounds more like Internet-facing Linux servers to me. > On Jun 24, 2020, at 12:05 PM, Kennedy, Smith (Wireless & IPP Standards) <smith.kennedy@hp.com> wrote: > > 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 > --- > Smith Kennedy > smith.kennedy@hp.com > > >> On Jun 24, 2020, at 6:53 AM, Michael Sweet via ipp <ipp@pwg.org> wrote: >> >> 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...) >> >> >> > On Jun 24, 2020, at 12:09 AM, Rizzo, Christopher via ipp <ipp@pwg.org> wrote: >> > >> > Maybe you have already seen this.
