I'd like to add my experience with HP.
Although I am very satisfied with my 17'' HP laptop and all my HP small format printers and officejets machines, I had a really bad experience with a HP 500ps. Back then we were using a Mac and AC 6.5 and after wasting many sc.meters of paper trying to get a decent, print we asked from the local GS distributor to give us a PC installation disk of ArchiCAD 6.5 in order to connect the 500PS to a PC and print using Plotmaker. This worked ok but we felt deceived as we wasted more money for the ps-Mac version! As I can recall there were no available Mac drivers back then and HP sold this plotter as a Mac compatible.
As for the quality of plotting (at least on a PC) it all comes to settings,quality of paper etc. Also I think that one needs to add a memory card to improve performance.
