4) If it doesn't work. Try to 'power drain' your printer - unplug all the cables from the printer and then press the power button for 30 seconds. After that, put all the cables back in the printer and turn it on.

5) Apply the same power drain and can do the same thing to the print server as well but make sure the print server doesn't reset all the settings.

7) If this doesn't work, then manually remove the printer's USB cable from the print server and put it back again after 30 seconds.

8) If the above tricks don't help you then uninstall the printer from your mac and add it again using the latest L120 driver.

@attymikeph I think you should try to use any adjustment program for your Epson L120. Browse this Epson adjustment programs and search for the L120 Printer model. Get the resetter from there and try to reset your printer back to its defaults. I think it will help you since you have said that you have the latest drivers and you have cleared any traces from the previous installations.
