T Hewlett-Packard Defines Inkjet Printer Resource

How Hewlett-Packard Defines Inkjet Printer Resource
For all Deskjet, Photosmart, Officejet, and All in One inkjet printers sold after July 2005, HP publishes print yield data based on the industry standard for measuring ink cartridge yield for inkjet printers (ISO / IEC 24711). (For laser printers, see in HP Toner ).

according to ISO 24711 testing recommendations, a standard set of five 20.32 x 27.94 pages is printed continuously until the cartridge runs out. Due to various circumstances, such testing conditions may not reflect the actual cartridge life. Therefore, when comparing ISO, the resource measurement standard should only be considered as starting point, not as an accurate prediction of the life of the HP printer and cartridge. The actual resource varies significantly depending on the content of the pages being printed, the frequency of printing, ink used in the preparation and other factors discussed below.

The five standard ISO pages shown below are a combination of text and graphics, and a combination of black and white with color.

ACCESS SEGMENTATION USING WIRELESS AP WITH PALO ALTO


On our wireless controller, we implement AD authentication (without certificates), and the wireless controller is connected to the
Deployment of Palo Alto Firewalls
Is it possible to get module to support a device that (sometimes) reports an invalid PCI identifier?Apple WiFi Profile - Prevent Changes
Enable access for wireless devices without WPA2 Enterprise
MikroTik Wireless Bridge - Bad Ping with Load
New Cisco AIR-1602I-E-K9 AP not working on some ports
Once the user authenticates through AD and joins the wireless network, the Palo-Alto Firewall can see that John Smith has joined the network from device A (some IP). Right?
Does the Palo-Alto Firewall also have the ability to search for groups to which John Smith belongs ? (ex Corporate, Room103, etc.)
If the answer to both of these questions is yes, can we then create a rule on the Palo-Alto firewall saying:

If the user belongs to the AD Room103 group , he may have access to certain resources on the network. (ie things in vlan 's Room 103 )

objective is to use a firewall to segment access. Therefore, when John Smith enters the system from any device (BYOD), he can have access to his resources without using any kind of machine authentication.

This cannot be part of “best practices”; however, this is not a concern. All I want to know is if possible.
