Hi LeeAAPL3,
For help with printing Google documents from your iPad, test the steps below found in the Google Support article here: Google - Print a file
"See & change how your document looks when printed
You can edit your file while in print layout mode to see how it will look when it’s printed.
- On your iPhone or iPad, open a file in the Google Docs app.
- Tap More .
- Turn Print layout on.
- Tap Edit ."
You can also find helpful information in the articles here: Use AirPrint to print from your iPhone or iPad and here: Print from iPad
If the Google sheet is the only document you're unable to print in landscape mode, reach out to Google Support to further assist. Get help with Google Docs Editors and How to contact an app developer
Cheers.
