I recently purchased the ImageClass MF269dw II. I need to be able to print over AirPrint from my phone. I can do this when the machine is awake, but it doesn't show up as active or as an available AirPrint printer when it's asleep. When I wake the machine up, it immediately appears as an AirPrint destination. I connected the printer to my Eero WiFi network. I turned off the power save on the network connection. It's connected via DHCP, but I previously tried a static IP address. Neither one worked when the Canon was asleep.
I also have a Brother color laser that always appears on my network as an AirPrint destination. It's just the new Canon that needs to be awake to print. I also noticed on my Mac that the Canon printer shows as offline, but I can still print to it. I don't have these problems with my Brother printer. I'm disappointed in the Canon but hope to find a solution.
I have a Pixma Pro-100 connected via Wi-Fi. It also needs to be powered on for the printer to be recognized. The printer has a power-off timer setting in the driver, but specifically states that printer will remain always on when connected via Wi-Fi. That appears to be the Canon design basis.
Has John pointed out he might be able to make changes to the printer's power management settings and for keep alive or awake.
I would also try assigning the printer a static or reserved IP on my network. This can be done on your wireless router. It only has to be done once.

I am using a static/reserved IP, but it still isn't visible while the machine is asleep. The max I can keep the printer awake for is 60 mins, but that is wasting energy. When in Energy Saver mode, it's like it doesn't exist. I don't get it. If this is a feature, I'm returning the printer as soon as possible. It's not functioning the way my Brother printer does. I need to be able to print without waking it.
