Printing with turboreport on Mac

I’m using the TurboReport class,on windows it works very well(i’m using 200DPI),print is good but on Mac I can’t get the same effect…at 72 DPI the print is blurry but it respects the A4 dimensions…I tried to get better quality setting more then 72 DPI and it prints with good quality but more then A4 dimensions.
Do you know a way to resolve?
