I bought this to not only use as a carrying case for my P11, but also storage. The case itself is roomy enough to properly hold a P10 or P11. The inner divider is adjustable via velcro. This allows for both types of printers and associated power adapters to be properly placed.The inside is also roomy enough to hold an additional box of supplies. There is an odd mesh pocket on one side which didn't seem practical for any purpose. There is an outer pocket on the hood to store other associated items. A strap is included to allow carrying the bag on the shoulder. It would have been better if a handle was also attached since I find the shoulder strap to be attached via cheap plastic.Overall, it is a good investment for your printer.
