Future perfect: finished by a future deadline
The invitations are not printed yet. Your friend needs them on Friday. You want to describe what will already be finished by then.
The short answer
Use will have + past participle when you look back from a future point at something completed: “By Friday, I will have printed the invitations.” By Friday gives the latest completion point, not the exact finishing time.
Choose the future checkpoint, then look back at the finished task.
Put have after will, then use the past participle: printed, written, or sent. Will be printing shows activity in progress; will have printed presents the printing as complete by the reference point.
Same project, different viewpoint
At noon tomorrow, I will be printing the invitations.
By Friday, I will have printed the invitations.
By then, I will have written the addresses.
Have stays have after will, even with she or he: “She will have finished.”

Common questions
A few useful details before you move on.
Is will finish by Friday wrong?
No. It also describes future completion. The future perfect makes the view from that later point explicit.
I will finish by Friday.
What follows by the time?
In a future time clause, normally use a present form, not will. Put the future-perfect form in the main clause.
By the time you arrive, I will have printed the invitations.
Take it into your day
Will have + past participle presents completion by a future reference point.
