How to print actual date on secured pdfs?

The creator of the PDF would have to have provided a field and script to the PDF for this purpose.

When I start converter it makes a pdf document at once. There are not any steps, where I could choose options. I searched preferences, but I did not find any ones to customise reating to this topic.
Where can I find the converter or where I can set proper options?

Besides it I have many documents only in paper. I will scan them to pdfs. What then? How to place in existing pdfs actual date?

I would be really grateful if you could help me.

Piotr,

The creation date of a PDF, if "built" by something to the PDF Reference,
will show the PDF file creation date in the Document Properties.
This is true no matter what the input (an application like Word or a scanned image).

To view a PDF's Document Properties: File > Properties > select Description tabPrior to creating a PDF you can configure many settings that will determine the
characteristics of the PDF.
In the Acrobat Preferences you can edit settings for how a file is converted to PDF.
Edit > Preferences > select Category "Convert To PDF" > select file format > click on the
Edit Settings... button.
Note that the settings that can be edited may be none or many.
This depends on the file format selected.

Also, if the authoring application has it, look at the configuration settings for the PDFMaker.

Another pre-PDF setup option would be the Distiller job options selected.

Once you have the PDF file created you can use Acrobat's tools to place a field on the PDF.
As George (gkaiseril) stated, you can use an Acrobat JavaScript that would populate the field
with the date.

So:
Step 1 = establish desired conversion settings
Step 2 = create the PDF
Step 2 = Create desired field or fields on the PDF
Step 3 = Use the javascript created for your task
etc.

Look over the following forums here at AcrobatUsers.com as they may provide more information
that is applicable to what you seem to desire:
The JavaScript forum
The Forms forums
The Security forum

Much useful information is available at the AUC Learning Center.

Be well...

Adding form fields is a different and distinct step from scanning. You have to add the form field and you will also have to add a 'Will Print' JavaScript action to the scanned image. This can be done on each PDF individually through the FormsTool and Acrobat's JavaScript editor, you could write a batch process using JavaScript to add the field and JavaScript to selected PDFs, or you could add a toolbar button or menu option to add the field and script actions.
