Are there still any new printers (postscript, laser) that are reasonable? Black and white printing is sufficient.
Also, actual example of a smart TV connecting to an unprotected WiFI: https://web.archive.org/web/20210912135232/https://forum.dev...
I have a strong feeling this is somehow related to our local office network, but... any wifi printers we have never 'wake on lan'. If I reboot the printer, it's connected. 30-60 minutes later, it will not respond to any network commands. It's on, and you can go insert USB stick to print, or make a copy on it, and it says it has an IP address, but it's essentially 'dead'. Although it has 'wake on LAN' set (or whatever the setting is).
Brother, but same issue with HP before that (and... someone else reports similar with their printer in their office too). But we have a dozen people plus more devices on the wifi every day without incident. Just something about the printers we've had over the last few years.
Have changed wifi routers at least once during this period as well to no avail.
