Network Issues - Cannot Access via Hostname & Wakeup After Sleep (Model: MF216n)

[hftsai256]

I have my printer connected by ethernet and the "only" way to get it operate is to go to Menu -> Network Setting -> Initialize Network Setting, and then re-install printer on my system. Once the printer goes into energy saving mode (sleep) it will never work again until I re-initialize the network settings again.

Also the hostname 'Canon59d87a' is not properly registered on my DHCP server so that I have to access the printer by IP address.

Greetings,

Try this.

Router:

Limit the scope of your DHCP pool: 10.0.0.100 ~ 10.0.0.200

Assign the printer a static IP above or below this range:

between

10.0.0.2 ~ 10.0.0.99

or 

10.0.0.201 ! 10.0.0.254

Result.  Printer will always get the same IP.  Router will never hand out the IP assigned to the printer previously to another device.

Thanks for your comment. It doesn't point to the core issue but it gives me a hint to figure out what is actually going on:

In brief, printer will turn off mDNS (Bonjure) after a period of time (before it went to sleep) and the only way to re-enable it is to manually switch off/on mDNS function. Yes we could always point printer address to http://<hostname>/ipp/print in CUPS backend. Unfortunately MacOS can only listen on mDNS (Bonjure) scanner.
