After some offline discussions I propose the following new attribute for JPS3:
The RECOMMENDED "printer-supply-info-uri" Printer attribute provides a "http:" or "https:" URI referring to a human-readable web page describing the current supply levels, part numbers, and other information, controls, and hyperlinks relevant to the Printer's supplies. The URI MUST use the “http” or “https” scheme with the printer as the destination host - external URIs are not allowed.
The ultimate purpose is to allow a client to display a printer's supply levels in a web browser (or other web-enabled UI) and (potentially) find or order replacement supplies. It can also provide remediation instructions (i.e. how to replace/refill/empty) a supply, etc.
