Well, I do not really know how to take advantage of that edit to /etc/hosts. Fortunately, though, Nautilus "smb://192.168.1.250/Public" lets me access the Shares folders. The printer I assigned an IP based on its mac ID. I guess that was necessary? I also went into the printer and manually set up the network (gateway, etc.) rather than letting DHCP or something else do it automatically. It was a couple days ago, so not too clear anymore. It works now and so does the NAS, therefore I'll mark this solved. Thanks to all for the input.
