render resolution problem?

[Nebuchadnezzar]

hello. I'm having a problem with the prints of some vray renders. the question is that in the screen it seems that the render have good quality but when i print it looks a low-res image. The printer is good so i assume that there is a way when i make the render and when i save it to improve the resolution of the image. Maybe i'm saying something stupid, but i don't now what else to do to improve the quality, and when i was making the renders i try to make it with so much good resolution as the pc allows me.
thanks in advance.

what were the dimensions of your image in pixels and what size were you printing it at?

If the resolution of rendered image is big enough to fit on your print without visible pixel edges, then you need to check the saved image if is with the same quality as in render frame buffer, it's posibly that you saved it in JPEG format with low size and even with high settings it's not the best choise.. in this case for print i prefer TIF format.
