In response to the first point, refer to the definition ...a user friendly name to be entered by the administrator. Long before IPP became prevalent, printers had or were given names. These might have appeared on startup or cover pages, perhaps on the user
interface after the printer was installed, and often were set via the printer Web page. I suggest that the "printer-name" attribute was intended to server that purpose. It was not unique, or appropriate for automatic search; it was to be set by the administrator
and no default value was specified. We should not be surprised by the variety of implementations; nor by the fact that this variety leaves the attribute unusable for any client function other than reporting the printer name. And the inconsistency in administrators
entering the name left that use questionable since other mechanisms also gave the printer a name. To fix this, we might suggest a default value. (It already is defined as writable)</div>

<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
If, other the other hand, we envision a new or additional function, we may need to ensure that the value is unique but still presumably user friendly. Depending on the additional function, we might suggest appending the hardware ID code to the administrator
entered value, or perhaps linking the value to some other unique attribute.</div>

</div>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">Greetings all, </p>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">Sorry I was unable to be present for the discussion! (I'm on "vacation" helping my elderly father pack his apartment.)
</p>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">I think we have a bit of a "chicken and egg" issue here. It may be that many clients have backed away from using "printer-name" because of the variability of the values printers provide. We can either deprecate that attribute / discourage
its use, or we can try to push it towards some consistency. These others are much more specifically prescriptive but not always pertinent:</p>
</div>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">- printer-make-and-model</p>
</div>
<div>
<p class="x_MsoNormal">- printer-dns-sd-name</p>
</div>
<div>
<p class="x_MsoNormal">- printer-device-id</p>
</div>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">The scenarios a client might use these and "printer-name" include constructing the "default name" it might give a persistent "old-school" print queue (e.g., Linux, macOS, Windows). I personally have a habit of setting the DNS-SD Instance
Name to something like "_Smitty ChickenLips_" and then I also set its .local domain name to a downsampled version of that: "smitty-chickenlips" so that I can identify it across client platforms regardless of how the queue gets set up.</p>
</div>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">The queue might be set up using a discovery protocol (DNS-SD etc.), or via a URI / hostname / raw IPv4 address / raw IPv6 address. One thing I'm concerned about is that, if the queue / printer is set up using one of the latter non-DNS-SD
methods, how would the user know that that is the device's name? For instance, if I set up the queue with "192.168.1.37", and the user read that off a config page or the printer's control panel, they have acquired the IPv4 address but may never have seen "_Smitty
ChickenLips_" or "smitty-chickenlips" or "smitty-chickenlips.local" before. So how will they connect the name to the device? </p>
</div>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">(I'd like to find a pathway to allow us to begin discouraging the use of raw IPv4 addresses, because DHCP leases can cause IPv4 address rotation, causing "printer offline" issues / stale queues, but in many semi-managed SMBs their networks'
DNS infrastructure and multicast propagation is just not reliable enough so they fall back to IPv4 addresses with fixed leases, I guess.</p>
</div>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">So what I might suggest for IPP Implementor's Guide v2.1:</p>
</div>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">- For printers set up using DNS-SD, the default queue name ought to be "<DNS-SD Instance Name / printer-dns-sd-name>"</p>
</div>
<div>
<p class="x_MsoNormal">- For printers set up by the user providing a hostname, the default queue name ought to be "<hostname>"</p>
</div>
<div>
<p class="x_MsoNormal">- For printers set up by the user providing a raw IP address, the default queue name ought to be "<IP address>" (gross for IPv6, I know...but that's what the user provided...)</p>
</div>
<div>
<p class="x_MsoNormal">- Regardless of how the printer / print queue is set up, it seems like a model name should be presented as well. How this gets presented to the user is a UX issue that is out of scope.</p>
</div>
<div>
<p class="x_MsoNormal">- All printers ought to present their DNS-SD Instance Name and their hostname and/or their current IPv4 address on their control panel if they have one.</p>
</div>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">Thoughts?</p>

Summary of discussion at June 20, 2024 IPP workgroup conference call:<br>
<br>
- Chris: Are we going to try to standardize this?<br>
- A: No, more curiousity<br>
- AirPrint/IPP Everywhere only require specific values for printer-make-and-model and printer-dns-sd-name<br>
- Bill: We might suggest a default? And recommend that the value be settable?<br>
- Uli: If there was a recommendation that would more strongly influence firmware design decisions<br>
- Mike: Not used by CUPS clients<br>
- Uli: Windows seems to default to using the printer-name value<br>
- Michael: I'll check<br>
- Ira: IIG2.0 says nothing about printer-name<br>
- Maybe file errata for IIG 2.0?<br>
- Mike: IIG can talk about client recommendations, IPP Everywhere 2.0 can talk about printer recommendations<br>
- Bill: What's the point of requiring printer-name if nobody uses it?<br>
- Mike: It has been required since IPP/1.0, and if we take a longer view maybe we could have something useful in the future?<br>
- Mike: Maybe IPP Everywhere 2.0 can make some recommendations/requirements<br>
- Bill: Suggest defaults<br>
- Mike: Also require it to be settable (EWS, Console, and/or Set-Printer-Attributes), not blank and not the resource path, etc. from the URI<br>
