Ive noticed that quite a few people are having printer problems recently, this should be resolved in the not too distant future with a UDEV, HAL and DBUS setup (See project Utopia http://lug.mtu.edu/slides/project_utopia.html gives an overview).
Those of you lucky enough to be running the latest gnome desktop will already have parts of Utopia (with the new Gnome Volume manager). Printing is in the works at the moment, but most common hardware is being included.
Finally, Linux will be hardware friendly
