I too have been using the HP DesignJet110PlusNR for the past 5 years. I do mostly residential and light commercial work and have found this printer to be very reliable. It does color and B&W and all drawing sizes up to 24" X 36". I do alot of preliminaries on 11" X 17" and 12" X 18" which can be done from a tray. Roll feed works well also if running several sheets of 24" X 36". Hope this info helps. Good Luck with the practice!
