Not vector, but it’s a PNG, which was the OP request. I also prefer SVGs, but PNGs work pretty well for me. And yes, they can be high-DPI sufficient for print.
Of course, I have a High-DPi monitor which makes it easier. But even on a 1080, you’d just need to go full screen (F11) and hide all windows. That would probably get you enough screen real estate for most grabs.
When I have needed matching images of fixed resolution (so they don’t pixelate), I’ve exported to PDF, zoomed to a preset percentage, and used Movavi Screen Capture. It allows you to fix a window size for capture, so you get exactly the resolution you need, every time.
