But a one printer one computer being a problem is precisely the issue in the thread at hand. Once the router reboots the printer changes IP address (since it gets a dynamic IP by default) and then Windows can't find it, hence the need to assign it a static IP.

This specific chain is about Bonjour and, more specifically, is a response to a claim that Microsoft is behind the times. The "Windows can't find my printer" issue is already addressed by other responses. Windows can find your printer even if the IP changes, assuming the printer wasn't installed in a way that circumvents that. (E.g. by not choosing to find it automatically and using an IP address against the on screen recommendations.)
