I understand your frustration, though the printer appears to have come out in 2010.  Very few companies will support electronics that old.

I couldn't find anything regarding error code 300 at this Support Link (you can search for error codes there).  Perhaps check out the troubleshooting section in the manual for any tips.

I am having the same issue. When I uninstall the printer from my computer and go to re-add, the printer doesn't even show up. The printer says it's connected to the access point, so the issue seems to be that it just won't connect to my computer. Help.
