Hi!

Finally resolved it by going into the Canon printers own panel settings
and found a USB port enable/disable function , not sure why the hell Canon
would even bother including such as feature.

Now you know. :-)

I would say that it is very unlikely that the print server device did any
damage to the printer or anything wrong. Nearly all of these devices just
pass data over the printer as though it were locally attached to your
computer.

The use of the incorrect print driver could have either confused the Canon
printer badly enough to make it stop working, or perhaps it sent a command
sequence that would normally never be issued to the printer in day-to-day
usage. From there, the printer might have taken the errant command to mean
"don't listen to the USB port at all".

It is far more likely that the USB port's controlling logic in the printer
was just confused by the garbage sent from the wrong printer driver.
