<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I'm trying to get thru the IPP Everywhere self-cert tests and fix any issues with our software. The device under test (DUT) fails the very first test:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">B-1 IPP Browse test: Printers appear in a search for "_ipp._tcp,_print" services.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The reason the device I'm testing fails, is because our device does not include ",_print" on the "_ipp._tcp" print service type.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I do not have strong knowledge of Bonjour requirements and MDNS itself, and I cannot find unambiguous requirements that say what "_print" is for and what it means to a client. In addition, the Bonjour Printing spec version 1.2.1 section
7.5 Advertising Services seems ambiguous, because it has an example (Apple LaserWriter) of advertising services without ",_print" in the first paragraph, and then shows "_http._tcp,_printer" service type example in last paragraph.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What specification can I refer to that explicitly explains what the purpose of ",_printer" is and why it is required? (Actually - after writing this question and then reading RFC 6763 section 7.1 Selective Instance Enumeration - "_printer"
subtype helps Safari Web Browser distinguish between a printer web page vs. a generic web server apparently, but that should only apply to the "_http" service - correct?) And on top of that, to my knowledge the ability to use Bonjour in Safari has been removed
a few years back). Where in the IPP Everywhere specification is the requirement the ",_print" be appended to printing service advertisements, and which service advertisements should it be appended to?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also, why does the test look for ",_print" when the Bonjour 1.2.1 spec and the RFC refers to ",_printer" as a sub-type on http advertisement?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
