2541-Printer Unavailable... Authentication Required

[Teeare1]

After many months of wireless printing, yesterday when attempting to print email from my Galaxy S8 via HP Print Service Plug In and HP Smart Print, I continued to get "printer unavailable"  "preparing preview", "authentication required" (but wouldn't accept our WiFi password although all wireless devices in our house are connected.  I've powered on/off, uninstalled/installed printing services, cleared print spooler data, and rebooted our router.  What is going on?

Welcome to HP forums.

Check printing settings and status on the Android device.

Make sure Android printing is enabled and clear the print spooler.

1. On your Android device, tap Settings , tap Connected devices or Connections, and then tap Printing.

2. Confirm HP Print Service is listed and the status is On. Tap Add service if the service is not listed to install it.

3. Return to the Settings, and then select Apps or Applications.

4. Select Show System Apps from the More menu .

5. Select Print Spooler, or tap Storage, and then select Print Spooler.

6. Tap Clear Data or Force Stop.

7. Restart the device.
