Create PDF from an Excel file without white margins

I have an Excel document that I need to save it as PDF but i have an image on the header and the footer that needs to be 100% long in the page. Whenever i try to save it in PDF, excel adds a white margin on the sides of the page.

I have already tried Page Layout > Margins > 0 all.

I also tried using PDFCreator, printing the document as a PDF files. The margin is still there.

Solution 1:

After thousand of tries, i foud a way:

I set all the margins to 0 (Page Layout > Margins > 0 all) and then i printed with the native Windows PDF printer: "Microsoft Print To PDF".

I didn´t even knew windows came with a native pdf printer but that solved my problem.
