Regardless of which method one uses, and the MS Print to PDF is a good one, this is generally the best way to save webpage content in a way that is readable outside a web browser. I use PDF Creator, but the concept is precisely the same, it is a virtual printer that takes what it's given to "print" and puts it into a PDF file.
With regard to the original query, for a personal credit report, I would be surprised if there is not a "save as PDF" option somewhere on that webpage, but perhaps not. I know I've saved my credit reports in the past using a feature on the reporting entity's webpage, not via PDF Creator.
