Gantt Chart Bars are too thin...How to make it thicker?

Hi,

Im using Primavera Contractor 5.0 and would like to have the bar show up thicker so that we can easily distinguish the baseline bar vs the progress bar and critical activity bar.

Is the possible solution to reduce the limits of the timescale to 3 years and also to tinker with page set up prior to printing?

Thank you for the help its a strain on the eye so far.
