How to print selected columns

edited 12/09/19 in Smartsheet Basics

I'm new to  Smartsheet and I have inherited some sheets from my predecessor. I'd like to print a Gantt chart and a grid.  My question is, how do I specify which columns will be printed?

When I print the grid it prints all columns I can see on the screen but I want to exclude some.

When I print the Gantt chart it only prints the task name and the timeline but I want to print other columns too, such as Assigned To and % Complete.

I've searched help and the community but I can't find anything on how to control which columns are printed.
