When I install my Canon MF632Cdw printer driver (v10.9.0) using Bonjour under macOS High Sierra 10.13.2, the printer works fine initially. However, after a few hours it shows as Offline and I can no longer print to it. If I look at the list of Bonjour printers in macOS Preferences (as if I'm adding a new printer), the MF632Cdw shows up only as a "Scanner". If I reboot either my Mac or the printer, it is fine again (Online) and shows up as "Bonjour Multifunction", as it should. A few hours later, it goes offline again.
Any idea how to fix this? I'm not sure if it's a Canon or macOS issue, but my other Canon Bonjour printer on the same LAN (an older MF4150) doesn't have this problem and is always stable.
