iOS AirPrint sends print-quality=high when file-type is photo even if user selects “normal”

Hi everyone,

I observed a behavior with AirPrint from an iPhone and wanted to confirm if this is expected behavior from iOS.

Scenario tested:

File type: Photo

Print-quality selected by the user: Normal

Observation (from packet capture): When checking the PCAP for the request sent from the iPhone, the print-quality attribute is always sent as high, even though the user selected Normal in the UI.

Question: Is this an expected behavior in iOS/AirPrint where photos are always sent with print-quality=high regardless of the user-selected print quality? Or could this be a bug?
