Digital BW, The Print

I'm a little curious of the results of a 1200 dpi laserjet for printing B&W 
copies. This would be from grainy negatives (e.g. tri-x). With 1200 dpi and 
100lpi, you would get 144 tones of gray. The question is - would this be a 
fair representation of a tri-x negative in terms of resolution and tone 
separation?
I assume that you'd need to print at least A4:s to A3:s to get a grain big 
enough to go fine with the lpi.
Has anyone tried?

Hans
