Usually, for a large image being printed smaller, you probably won’t see much difference between resizing it yourself and letting the printer software scale it. The result depends on the printer, driver, and software, so there isn’t one universal answer.

A few practical points:

• Downsizing a large file for print is generally forgiving; differences are often hard to notice.
• Upsizing a small file can show more difference, depending on how the software resamples the image.
• Matching the paper also involves aspect ratio, not just size. If your image shape doesn’t match the paper shape, cropping may be needed.
• Sending an extremely oversized file isn’t usually beneficial; the printer will still print at whatever effective resolution it can use.

Best advice: test your own setup. Print one version resized to the final print dimensions and another using the original file with printer scaling, then compare sharpness and overall appearance. That will tell you more than a general rule, because print pipelines vary.
