And that's not even getting into the self bricking when a 3rd party ink cartridge is loaded and other bad behavior by multiple makers (not just HP). And that worked much better than having all these devices for which you need a custom special driver that likely will stop getting updates one day that in turn imposes an artificial end of life on your printer.
I really miss the days when a printer was either a dumb text terminal with some control codes or a PostScript capable printer at a certain level of PostScript language. This whole thing appears to exist just in case the printer is on some corporate network that doesn't connect outside while the PC might likely be able to batch up some analytics to HP whenever it does have an outside connection, say when the user is on vpn. Something it does automatically to the HP Instant Ink API outside your network anyway.
I'm speculating here but afaics the health monitor that was running just tells the printer to report back ink levels. And most of the time, this suite isn't running (once the wake up permission is removed) and none of the other machines have any problem continuing to use the printer. The other devices are printing fine with regular drivers, but the PC has this whole suite of stuff on it that doesn't just print, it scans, faxes, makes card designs, checks ink levels as though there isn't a button on the printer for that, and has a"troubleshooter" "wizard". Like imagine a household with a Tango printer where the device is used weekly by Macs, iPads, and Android phones and maybe 3 times a year by a Windows machine. Not sure which printer exactly or why it's not working but afaics this software didn't impact my Tango at all. I tried unchecking the task's ability to wake the machine from sleep. Update: No, turning off background apps did not stop this task from being scheduled again for a later date. Owner Supplied Reason: Windows will execute 'NT TASK\HP\HP Print Scan Doctor\Printer Health Monitor' scheduled task that requested waking the computer. Owner: \Device\HarddiskVolume2\Windows\System32\svchost.exe (SystemEventsBroker) PS C:\Windows\system32> powercfg -lastwake It doesn't impact printing, but I wonder if it has some unintended behavioral issues, or isn't even likely to help with random waking up of the PCs. I'm hoping using the windows' app settings for that app to turn off background apps on it will help. I can't seem to find any support article about preventing it, nor any setting in the app that might stop it from doing this every few days. It doesn't seem like it really needs to since the printer in this case is a network printer mostly doing its own thing. It seems HP Print Scan Doctor is related to the HP Smart windows app and it likes to wake up a PC some time around 4:50pm.
