Turn off Desktop printing. The easiest way to do this:
go to System Folder>Extensions.
Select in the View menu 'By list' to put everything in alpha order
Locate the Desktop printing files (2 of them - Desktop Spooler & Desktop PrintMonitor)
Drag them to the desktop.
Now Close the Extension folder.
Drag those two files to Extensions (disabled) folder.
Restart the computer and immediately hold down the option key and the Apple key.
Continue to hold down those keys until you get a dialog box asking if you wish to do a desktop rebuild. That will appear after the extension icons load at the bottom of the screen.
Release the keys and click on Okay.
Now you will see the printer icon on the desktop with an X on it. Just drag that to the trash.
Next - go to the Chooser and select the printer and port.
You should be printing now.
p.s. sorry for the delay in answering you. I am playing catch up since a major power outage.
