The problem I've just had with adding support for my canon printers is that
libinklevel can't know what kinds of ink some printers have, so either HAL
must ask for the right ink levels  (black, photo black, colour, yellow ect)
or we'll have to have the information stored some place and modify
libinklevel to use them.

Or maybe just bolt on a dbus interface to libinklevel and then use it

Yes it has, which is why I thought HAL would be a great place to  enable
information to be collected, it has access to model information and use data
that would make it impractical for some generic or generalised tools store
huge tables of information.

Markus, what do you think?
