What i may print pdf from standart invoice module?

I don’t know that anyone understood your question.

You click on “Generate PDF”.

Then it asks you to “Create PDF Template or Select An Invoice”

You create a PDF Template.

When you try to link the PDF template that you created to the Invoice form in Studio, you’re getting some kind of an error message.

Can you please try to translate the error message for us? I haven’t spoken Russian since I was 5.
