Impractical is: There's no switch to turn off - so another standby unit.
What you should know: There is an easy to use mode in which you still need to adjust certain things (Important: use - whether text, image, graphics for printing or text), and there is a erweitereten mode in which a few more parameters are adjusted. The default setting for the scan buttons you should optimize for their own purposes.
Conclusion: A really useful device that decreases as it prepares a longer work. 4.5 Stars
