Printer won't connect
Printers lose touch with computers all the time, and a few restarts plus a fresh setup usually gets them talking again.
Be careful: Only get printer software from the printer maker's own website or the official app store. Ads offering 'printer help' or asking you to call a number are often scams.
What to do
Step 1: Turn the printer off, wait 30 seconds, and turn it back on.
Step 2: Restart the Chromebook.
Step 3: Check the printer is connected to the same Wi-Fi network as your Chromebook.
Step 4: If it still won't print, restart your Wi-Fi router: unplug it, wait 30 seconds, plug it back in, then wait a few minutes.
Step 5: Open Settings and search for Printers. Remove your printer from the saved list using the three dots next to it.
Step 6: Look under the list of available printers, find your printer, and click Save or Set up.
Still stuck? If the printer can't join Wi-Fi at all, use its own setup screen or the maker's official app, or contact the printer maker's support.
