Please someone tell me the speed of this plotter can be fixed. I have been researching online and many people complain of how slow to print it is. I have tried printing over the network, USB and no matter what it takes close to an our for a 500 mb file to print. Yes I know 500 is large, but should not take that long. Most of the time the print times out and printer reports flushing print job because of an error.
