Well we've been using the plotter for about a week now and everything is smooth sailin'. Easy to setup. Instructions were straight forward. True to its claims it prints FAST and without hiccup. So far we haven't had to do any high resolution prints yet so I can't yet comment about that.
We have printed from Archicad, Sketchup & Adobe Illustrator. The printer is setup on our network for 5 users, plugged it right into our Airport Extreme Router...voila, everyone had access. We purchased it directly from HP, they delivered it in 3-days FREE shipping. We paid $6,592 for the 44" ps model.
Of course I couldn't officially recommend it until after we've used it for sometime but so far we are VERY happy with its performance.
Great BUY!!!
