I hope I do not annoying you and hope this is the last question : Inform me how I can
able/disable Bomjour ?
First, did you try "scanimage -L" ?
Second, the function to enable/disable Bonjour is a printer function. The HP 4620 has an
embedded web server that you can/should access to check and make settings changes.
Your interface may look different than mine since I don't have the same printer. But
here
is what my interfaces shows.
