How to reset the GPSU21 print server back to factory defaults
To Perform a Factory Reset:
Disconnect the Ethernet cable and any devices connected to the print server. With
power still connected hold the reset button for ten seconds. While continuing to hold the
reset button unplug the power from the print server, continue holding the reset button for
another ten seconds. While continuing to hold the reset button plug the power back into
the print server and hold the reset button for another ten seconds. At this point you can
now release the reset button and unplug the power from the print server again. Allow
the print server to sit for another ten seconds, plug the power back into the print server.
Once you reset it here is how to set up again.
There is a reset button. Unfortunately, it didn't occur to me that I'd need to reset the device.

I guess RTFM is sometimes the right answer:
No worries.
Yup. That's why I was saying this wasn't really an OpenWrt issue. But I'm glad that you're back up and running again!
I would create a folder and download everything you may need in the future. I doubt they will continue to serve those pages for a few more years. e.g. a firmware update.
It's done.
