It's probably not normal to get excited about a printer, but I am about my new Samsung C3010DW color duplex. I print a lot of manuals and the speed and quality of this printer is amazing! My previous laser printer was also a duplex, but it lacked speed and quality of print and I think it was losing its memory controller.
The only thing I would like to see different, is a more expansive printout of the features. Maybe I just missed it.
