What is notable is that there are way more events on High Sierra than on Sierra, which tells me that the mDNS code in High Sierra may either have a bug and drops devices or be way too aggressive in removing devices much sooner than Sierra did: If you do a dns-sd -B on your system, you can see your Bonjour device events here is a log of mine on High Sierra. My Canon PRO-100 printer is hardwired and is configured using the Canon IJ Network protocol, which is also doing device discovery (no hard coded IP address) and that printer has been rock solid on by Sierra and High Sierra. I also have configured a printer using fixed IP and LPD protocol for may Canon LP6230 printer, which was also going 'offline' often. I have been doing some experimenting and, like others here, have found that specifying a hard-coded IP address for both the printer (using LPD protocol) and the scanner (in Canon's MF Scan Utility) dramatically increases the reliability of the MF733C printer/scanner. iMac printer setup is connected to HP using AirPrint.Waking my printer from Energy Saver mode doesn't connect it to the print queue. My HP printer is set to Energy Saver mode, but never auto power off.macOS High Sierra 10.13 (supplemental update installed).I didn't have this problem in macOS Sierra. I have to reset the print system in High Sierra and reinstall the printer each time. Even when I can't print, I can use Safari to browse to the printer's internal setup webpages so the printer is connected to the network.

The printer is connected my wi-fi network with a good connection. This happens every time I don't use my iMac for a while. When I come back the next day, and printer something, it's stuck in the print queue which says it's trying to connect to the printer.

When I install the printer under Printers & Scanners system preferences, I can print to the printer at first. Since upgrading to High Sierra, my iMac has recurring problems with losing the connection to my wi-fi printer.
