This post shows how things look using Mozilla Firefox on a Windows 10 computer. Some details might be a tad different on different browsers and I confess to complete ignorance as to Mac computers, but hopefully the Apple folks among us will know how to interpret the basics to fit the Mac.
Go to your Consultant Planner and click the title of a lesson plan you have already created. In the top right, click Print.
This opens your print dialog box. At the top, you will most likely see your default printer. Click the little down arrow to the right of it to see other options.
In the list, click Microsoft Print to PDF. I assume an Apple product has a similar option. Then click OK.
On the next screen, tell your computer where to save the lesson plan and give it a name.
Choose where to save it using either the list on the left or the drop-down arrow at the top. In the File name field, give it a name that means something to you--something like Johnson Lesson 1. Click Save. And... ta da!... you now have a PDF version of your lesson plan that you can save in a folder or that you can email to the member you are working with for them to easily refer to in the future.
By the way, the next time you want to print something, your computer will probably default to the save as PDF setting on your print dialogue box, so you'll need to re-select your printer.
