Hi,
Have just updated to the latest 4.0 sheets.
What a difference - they print in colour and have the black backing to the Ability & Weapon box's etc.
Previously the black backings and the contents turned to a hard to read grey colour when I tried to print them.
I am still using Google Chrome, but the change is like night and day!
Well done "AncientOne"
Should be made an official output choice for Pathfinder character sheets.
