Can page post date be changed to page last update date

Hi –
We like the WP Print plugin. Very easy to use. The print page displays the page post info, person name, date, etc at the top of the page just beneath the page title.

This is the page post text:

“Posted By jillkt On December 15, 2016 @ 10:24 am In P-5d. UW Personnel,P-6. Budget | Comments Disabled”

Is there a way to remove the page postinfo and instead print the page last update info?

Thanks,
UW
