It prints good queality pictures even in fast normal mode and the speed is even faster than our printer at work.

None

This is the best printer I have ever owned and I have owned quite a few. I even thought of bying another one before they go of the market. I used this printer for direct marketing and choose it because of its speed (pages per minute is 30) I have printed a couple of thousand pages in the 3 years that I have owned it and would recomend it to any body that wants a good quality printer.
