This solution works by leveraging the Wi-Fi Direct standard that was developed last year by the Wi-Fi Alliance and the Apple AirPrint technology that eliminates software or driver installation on Apple mobile devices. The user simply needs to connect to the Wi-Fi network that the printer advertises, then print.
Pros: Easy printing from mobile devices in the enterprise
This should help simplify support for BYOD (bring your own device) initiatives. Since BYOD typically is also designed with security restrictions around corporate network access, and printers are usually distributed throughout the network, providing access to those printers would be a management headache to say the least.
Also, mobile device printing via Apple AirPrint on a corporate network is not usable at this point due to protocol limitations that prevent printer discovery and access across layer 3 network boundaries. The ability to connect directly to the printer and print documents will allow immediate adoption of AirPrint in the enterprise.

| HP Wireless Direct Printing is Easy using AirPrint (but appears to lack any security) |
Cons: Unproven security
The security issues involved with a Wi-Fi network being advertised by a printer that is directly cabled into your network are significant. Printers have historically been easy targets for attackers to gain access to corporate networks due to their lack of focus on security. Just look here! By allowing direct wireless access to the printer, enterprises risk exploitation of numerous printer vulnerabilities which could result in broad internal network access for an attacker.
HP's implementation also appears to use an open Wi-Fi network, which makes the risk even greater! The Wi-Fi Direct faq states the use of a separate "security domain" from the corporate wireless network. What this means is that security of the Wi-Fi Direct connection can be different (and simpler) than security required to access the corporate network. But that doesn't require an open connection. Wi-Fi Direct supports strong WPA2 pre-shared key security and ease-of-setup using WPS. However, HP's documentation implies a wide-open wireless network.

Recommendation: Wait and see
I can't provide a solid recommendation on this technology or use in the enterprise until I learn more about HP's implementation. I have more questions than answers at this point. The prudent path for enterprises will be to wait and see what is discovered about this solution by the community over the coming weeks / months and engage your HP account team to learn more about the solution and security features.
Additionally, verify if the printers that your organization are purchasing support this technology, what the default settings are, and what controls can be put in place to prevent use of this feature until its use is appropriately secured and approved.
Cheers,
