OK, I do this large format printing stuff for a living, so here's my advice:
the printer resolution of 1440 dpi, 2400 dpi, 2880 dpi or whatever is NOT what you should be aiming at; for example, throwing anything more than 360 ppi (pixels per inch) at a 1440 dpi (dots per inch) printer will achieve nothing in terms of print quality.
I work at 240 ppi for 99% of the work I do; 360 ppi for images with REALLY fine detail; 180 ppi is ideal for most photographic / CGI images. A 3000 x 5000 pixel render should be perfect.
Have you thought about interpolating rendered images? You can get away with a 200% size increase in Photoshop in many cases (using a dedicated interpolation engine such as PhotoZoom Pro or Genuine Fractals, up to 400%).
