Dear Amester,
Thank you for your question. The model you have shared is not listed inside the tested devices. To see a list of tested compatible devices you can visit > http://www.wacom.com/en-us/comp (this list gets constant updates). On the other hand, this does not mean this pen is not going to work for you.
The Bamboo Ink counts with dual technology built in. It can either work with AES Pen technology or MPP (Microsoft Pen protocol), for this you will need to confirm with Asus in this case if the model that you have has either technology.
Now to answer your other question, Pen pressure will work only for those devices using AES Pen technology and to activate that side, you will need to install the driver for it.
Hope that helps, if you have any further questions or need technical asistance don't hesitate to reach out here > http://support.wacom.com/
