Well friends. Nuked the old printer que/setup. Move the connector to a new USB 3 empty plug in used the command above to discover and set up the printer, it is the default printer. When setting up I selected to send a test page to printer. Printer lcd screen reports Printing document, but it is not. Canceled the test page print job, selected some random text off a web page to print still no joy. What to do next? Thank you for your continuing help.
