Our old Calcomp pen plotter is on its last leg so to speak. A company who refurbishes plotters and sells them with a warranty suggested that we buy an HP750C. We plot two-dimensional drawings in color, up to 36" x 24", but we also plot A, B, and C size drawings. Our volume is low, so we hand feed the paper. I read somewhere that it was time consuming to hand-feed paper into the 750C. I'd be curious to receive any feedback on this or other plotters that would seem appropriate for our requirements. Thanks in advance.
