Bought for my daughter's HP Sprocket printer as she drops things quite easily. It offers some protection, but I wouldn't trust it for fall protection. Also, the casing works great as you can easily slide the sprocket in and out. It's reversible so you don't have to worry about it being inside out.
Pros
Perfect Size: Fits HP Sprocket and HP ZINK Photo Paper.
