I realize that my questions are perhaps tangential to the primary purpose of the IPP Firmware Update Extensions document, but the allusion to firmware as a resource handled by the IPP System Service under
<b>Directed Firmware Update (Section 4</b>) led me to revisit that document, and I would appreciate someone clarifying a few points.</div>

Firmware Update Extensionin the Directed Firmware Update discussion states “If the Output Device implements the IPP System Service [PWG 5100.22], then it can receive the Firmware Update from the Management Device”</li><ol style="margin-top: 0in; margin-right: 0in; padding-left: 0px; list-style-type: lower-alpha;" data-editing-info="{"orderedStyleType":5}" start="1">

<div role="presentation" class="elementToProof">My understanding is that the System Service is more akin to the Management Device in Figure 1 than a printer, and is intended to support multiple printers.</div>

The operations applicable to firmware download (Create-Resource, Send-Resource-Data, and Install-Resource) are. I believe, System Service but not Printer operations.</li><li style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0); line-height: 115%; margin: 0in 0in 0in 1in;">
Would it be valid to implement some subset of the System Service capability in an individual printer?</li></ol>

<div role="presentation" class="elementToProof">If one did implement a System Service (which seems to me to be a very useful capability), and created, downloaded, and installed a resource in the System Service, how is this resource transferred to individual
printers?</div>

And finally, the System Service absorbed much of the functionality of the previously defined Resource Service. I was of the impression that proprietary schemes were typically used for downloading resources. Out of curiosity, has there been any degree of implementation
of the System Service in the industry?</li></ol>
