Good solution, Mike. That sounds like an excuse from Canon; it sounds
like a bug! IP ought to be IP, right? Is its TCP stack broken or what?
I had a Xerox that didn't have that particular limitation (one of the
early solid inkers), but it did fail completely with any mask other
than /24.

What I ended up doing for that printer, and what might also work in
this situation, is NAT on the gateway, on inbound traffic -> printer.
