I just turned and looked aroud me.  I have an HP 4315, Epson Photo 785EPX. Canon MP150, and Samsung SCX-4100 here in the office (I have 3 computers setting here. 1 is Fire Dept's, 1 is just for internet use, and 1 is business only with no internet access.  That's a physical firewall between it and the internet.

I am very pleased with  my Samsung.  Once it gets the first copy out it is ooddles and gobbs (technical terminology) faster than the inkjets.  Cost per copy is considerably less as well.  Only down side is it is black and white only. 

What I have done is use the Samsung as my default printer on 2 computers ... one via USB and the other via parallel cable.  Both computers also have a color inkjet hooked to them.  So if I want color I choose the inkjet, if I want black and white it defaults to the laser.

I was hesitant about a Samsung, but it's been here getting close to a year and been flawless.
