This seems to be a much newer printer and does have Apple AirPrint.
AirPrint was
introduced in 2011 to support iPads.
https://openprinting.github.io/driverless/01-standards-and-their-pdls/
summarizes the differences in the various Driverless Printing
implementations. PDF is supported
across the board, but there are several raster formats and also PDFm which
is viewable with PDF viewers,
but tailored for the capabilities of specific printer models. AirPrint and
IPP use different raster formats,
and Apple could change the details in the future, but currently it doesn't
appear to be a big deal as most
printers support both and conversion from IPP to Apple raster formats just
requires simplifying the header,
so probably easy to implement in the printer to gain IPP support.
I just thought to check the web interface that the printer provides
and I
see that connection protocols can be turned off.
This is at http://{printer IP}/net/net/protocol.html

The only two that are unchecked for the above list are "FTP Server" and
"Proxy".
