Ray Trace Size/DPI for Photo Quality 8 x 10 Prints?

[cwrm74]

Tomorrow I need to print some "photo quality" ray trace images of a model we are working on, on 8 x 10 paper. The printer will be a Canon Pixma 100, which is advertised as having 4800 x 2400 resolution. (I haven't used this printer yet). 

 

My question is: for an 8 x 10 print, what settings should I use for the ray trace, for image size and resolution (dpi), in order to ensure maximum possible quality and resolution in the 8 x 10 print?

 

I don't want to unnecessarily waste ray trace time, as we have a lot of images to generate, but I also don't want to give up some of the resolution the printer would be otherwise be capable of.

Assuming you will set up your raytrace to an 8x10 aspect ratio, then divide the lowest resolution number (2400) by the least dimension (8"), which gives 300dpi.
