</span>No.<br>

<br>
</span>Yes.<br>
<span><br>

<br>
</span>Perhaps, but the key is to be able to share/mirror the resources to the Infrastructure Printer, so that both the Infrastructure Printer and Clients have access to them.<br>
<span><br>

<br>
</span>The Infrastructure Printer is providing the storage, so it knows how much storage space is still available.<br>
<span><br>

<br>
</span>That might be a useful addition to the RegisterSystem operation (StaticResourceKOctetsRequested?) but probably isn't something we can add to IPP INFRA since we don't have a RegisterSystem equivalent.<br>
<span><br>

<br>
</span>Because we don't need to upload firmware/executables from the Proxy to the Infrastructure Printer, and the template category is still undefined.<br>
<span><br>

<br>
</span>For IPP INFRA, you look at the printer-icc-profiles, printer-icons, and printer-strings-uri attributes. (and conceptually the WebDAV PROPFIND method to list the full contents of the directory...)<br>
<span><br>
> What controls what has access to the contents and for what purpose?<br>
<br>
</span>As specified in the current spec, PUT and DELETE requests need to be authenticated as the proxy user (same auth requirements as the Proxy operations). As for the contents and purpose, there is no explicit set of restrictions beyond the filename and storage limits.<br>
