Re: [IPP] What value do IPP Printers provide for "printer-name"?

[Anton Thomasson via ipp <[e-mail]>]

Hi

I too expect something human-useful here.
Looking through my user-supplied attribute dumps, i see most printers doing
something decent; mostly model-based.

Some interesting outliers:

   - Xerox WorkCentre 6515: "192.168.1.74"
   - Various Brother printers: "" (empty string)
   - Brother VC-500W: "print" (from /ipp/print presumably)
   - EPSON SC-P900: "ipp/print"

Br,
Anton
