What it amounts to is this: if there is a barcode then the USPS employee can scan it and trace it, so it is a known source. If it is handwritten there is no way to source it, so it is then known as an anonymous package...which equates to a suspicious package.
If it is possible, I recommend printing your own labels to save time.
