However the use case important to Xerox is where the client must
have the scanner deliver the scanned documents directly to the destination. (e.g., scanning a contract and delivering is securely to the destination.) The ability to discover scanners that support push without interrogating all the scanners in an enterprise
environment is needed. We eliminated seven of the text records from the discovery message. This leaves 4 mandatory, 2 conditional, and 2 optional. Adding this one should not be an undue burden. I can live with a Boolean but would prefer a list of schemes.
A list fully populated with the defined values would be “http,https,ftp,ftps,smb,ipp,ipps,mailto” which probably comes down to about 45 bytes for the text record.<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Pete<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Impact","sans-serif";color:navy">Peter Zehler</span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><br>
