Comment 29 for bug 813482

That's probably because the USB printer driver was loaded which in turn means that at least the mode switch was successful.

To see in more detail what is happening when you re-plug the printer, call the "dmesg" shell command afterwards.

For printing, you might have to ask at a different place; I don't know anything about that. Just to clear things up: me and Draisberghof are identical ... It's my web site.
