How can I print an estimate that shows the mark ups?

Welcome to the Community, Psmith. I'd be willing to help you. 

I'll walk you through how to add the markup label to your template. Here's how:

1. Go to the Gear icon and choose Custom form styles.
2. Look for the invoice template you use and click Edit.
3. Then, select the Content tab.
4. Then, choose the Table section.
5. Scroll down to the bottom part, and click Show more activity options.
6. Put a checkmark in the Show markup on the billable expenses box.
7. Click Done.

The Community always welcomes you for further inquiries about custom form styles. Have a great day ahead!

Thank you very much.  However, is there a way to do that on an estimate or can it only be done on an invoice?
