I'm just wondering how to go about doing this remotely over a network with mutiple CUPS servers running on different machines. My CUPS server just flat out told me that the remote CUPS server didn't do duplexing. Is a remote CUPS server able to report what a printer supports to a local CUPS server?

Yes and no. Yes for the attributes defined by the IPP rfcs and/or the
official CUPS
documentation, the cups server queries the printer by IPP request for
the supported
attributes, and for local non-IPP printers it looks into the PPD if a
corresponding
option is supported. No for attributes that are sort of "user defined"
and completely
evaluated by special filters (or modified standard filters) and are not
contained
in any supported spec or PPD.
