You will not be able to print.

If you don't already have PDF copies of all returns, I would generate them now before your FastPath expires.  When I did this I turned on most of the optional forms/worksheets in the Preparer set and enabled printing of SmartWorksheets then I did a batch printing from HomeBase.  Depends on how many returns you have, you may want to do them in batches but I just did Select-All (Ctrl-A) and batch print.  Took a few hours so don't plan on doing anything else with that computer.

You can also just generate a Filing Copy PDF for everyone if you think you're going to provide clients with copies of their returns.  I make it clear in my engagement letter that the client needs to keep their own copies but you do you. 🙂
