Make PNG Print-Ready & Scalable

I have one existing PNG that I need converted into a fully print-ready file for Flyers, Banners, and Business cards. The artwork itself must remain exactly as it is—no color tweaks, text additions, or other edits—just prepared so it can scale cleanly to any size without pixelation...
