While most people who scan a lot of images would want a single-function best flatbed photo scanner, almost all multifunction printers (MFPs), also known as all-in-ones (AIOs), have a flatbed scanner that can scan picture prints and other materials.
Depending on the hardware and software used, the efficiency of their photo scanning varies significantly. In terms of scan efficiency and/or picture-centric functionality, they fall well short of single-function photo scanners.
