While I'd likely start with a LAN connection, it's good to know that both can be used together. First, USB seems more reliable in general, and second, I've noticed a few software features supported only using USB (admittedly obscure features).
Important to me now is the question about (lack of) paper jams. Long ago, I had a printer from a different manufacturer with a U-shaped hairpin paper path. Jams were so frequent, I had to use its page-at-a-time manual feed slot a lot. The MG6320 doesn't seem to have that emergency work-around. Hopefully, paper-handling reliability has improived in the industry since my earlier experience.
On the net, I couldn't find reviews from people who have used the MG6320, so thanks for the comments in this NG.
