What caused it was the inability of Bonjour to traverse a bridge. (Bonjour's TTL is 1, and cannot be bumped up.) I reconfigured my internal network and gave my printer a constant IP address (handed out by my router) instead of depending on Bonjour to do it all, and the problem went away. Printer is USB only. The router in question has a USB port, and support for network printing. It exposes the printer to the network as Bonjour. I have no idea how to give an IP address to a USB printer, nor any idea how Bonjour works internally (other than that it is supposed to hide the concern about where on a network something is).
