VIVO Floating Wall Mount Tempered Glass Shelf for DVD Player, Audio, Gaming System, Streaming Devices, White, MOUNT-SF011W

Will this hold a brother 4-in-1 printer?

Is there a way to mount this with command hooks? I can only use command hooks on the walls where I live. Will be holding a very small projector.

Whats the best way to hide the cables?

Can this hold the weight of a good receiver?
