How does a Universal Print Ready Printer communicate with IPP infrastructure printer?
The Universal Print Ready Printer is acting as an IPP proxy, is it correct? According to PWG 5100.18, the IPP proxy inside a printer should send Update-Output-Device-Attributes to the Infrastructure printer.
After obtaining Device Access Token following https://learn.microsoft.com/en-us/universal-print/hardware/universal-print-oem-printer-device-token , which URL is used to post Update-Output-Device-Attributes with that device access token?

Hi,
I successfully register a printer. Then try to use printer device token as the authorization bearer to post https://print.print.microsoft.com/printer with Update-Output-Device-Attributes operation. But the response is "Required security scope does not exist". The scope I got from user token is below. Do I miss to request other permissions?
https://print.print.microsoft.com/PrinterProperties.ReadWrite https://print.print.microsoft.com/Printers.Create https://print.print.microsoft.com/Printers.ReadWrite https://print.print.microsoft.com/PrintJob.ReadWrite
If I use user token as the authorization bearer to post https://print.print.microsoft.com/printer with Get-Printer-Attributes operation, I can get the correct ipp response.
Hope anyone can help me to resolve the failed to Update-Output-Device-Attributes operation issue.
