Comment 63 for bug 29050

Hmm yes, I may have an idea ! :-)
Try loading the "ppdev" module ("sudo modprobe ppdev").

I had forgotten about this module, which I had added manually, because of a program I installed, which required this module so as to gain (direct) control of the parallel port pins (not for printing). It creates /dev/parport0.

I fiddled with it a bit, removing and inserting this modules a few times, it seems to indeed be responsible for my good luck, so give it a try !

Now that helps, but that's still only a workaround and not a proper bug fix : why does one now need to load this modules to get that printer to work, when it wasn't necessary in Breezy ?
