Your last statement
I believe that I did the same procedures with the HP3320 printer.I'm running out of options. I want you to try the HP3320 as I think that there is another way (the puppy way) to have the 6450 printing without CUPS.
I read your instructions above to mean that I should now reconnect the 6540 printer, and await whatever instructions you have from "the puppy way"...so I can try those on the HP6540.....unless you discover something with the second attempt with the HP3320, and wish me to try something over or new with that printer.
I await your commands
