If you set

1. A section for 8 bars
2. Opt->Screen/Bars 3 /screen

a) The notation screen will display
a screen of 3 bars + a screen of 3 bars + a screen of 2 bars = total of 8 bars
during playback

b) The final printout will be also on paper
3 bars + 3 bars+ 2 bars = 3+3+2

The print out should not follow the settings of display.
They should have different settings.

Thank you for your time!
