Summary: I have owned 2 HP plotters over the past 15 years. My last Designjet 800 was a workhorse, lasted for 10 years and croaked a few weeks ago. I needed a plotter fast, so my choice was the Designjet T520 because it "looked" like the plotter to replace my 800. Unfortunately, it had problems right out of the box. The printhead cartridge was fouled up and would not work. The plotter is not built the same as the old models, not as sturdy. It just seems cheap looking.
Summary: Still testing the new product, and of course would like it to print like my old Plotter a designjet 430. So far, it doing what I need it to do, just tweeking and trying to find out how to print with out having to press the continue to print on the screen, because it detects something is wrong. Like I said Overall nice plotter, being an HP product I know it will last like my old plotter.
Summary: We had the HP 130nr for about 8 years and loved it for our small office. It recently died and we purchased this printer as a replacement. Haven't used it a lot yet, but so far it seems ok on the printing side. The one down side is that it does not have printing trays like the 130nr did. It comes with a stand, which we are unable to use due to office layout, and that I'm sure adds to the price but purchasing it without the stand is not an option.
Summary: Nice quality prints. A colleague of mine also bought this printer and was having some trouble with print quality that I did not experience.I suspect it might be the PDF created by Autocad. I use the Mac print utility for PDF creation. My main complaint is that the roll needs to be unloaded to print from the multi sheet tray and I assume the same is true for single sheet loading. Also, the machine is not smart enough to orient the document.
