I have several iPads (1 and 2) but they are all Wi-Fi only models so I'm hoping someone can answer the question for me.

 

On a 3G iPad2 can you browse the web with Safari, using the 3G connection, and print a web page on an HP AirPrint-ready printer connected in ad hoc mode?

 

The HP printers work great with my Wi-Fi iPads. I have been testing the OfficeJet 8500A. Right out of the box I turned it on and it automatically appeared as a new ad hoc network in my iPad Wi-Fi settings.  I selected that network and was able to print.  Using the HP iPrint Photo app I can also scan directly to the iPad.  Of course, when connected to this ad hoc network I can't access the Internet.

 

I'm hoping the 3G Internet access and Wi-Fi AirPrint can be used at the same time, but I have no way to test it, and I've been unable to find any information online.

iPad 2, iOS 4.3.2

    You can only be connected to one at a time.  If you connect to 3g to view the article, then switch on wi-fi in the settings, you should be just fine.  Using Wi-Fi and 3G at the same time I believe is not possible (without jailbreaking)

    No you can't have both a wifi and a 3G connection at the same time, it's one or the other , what your asking would require you iPad to be able to handle two ip addresses from a wifi and 3G connection at the same time. I think you should reconfigure you printer to work on you wifi network.

    Hi Robert, there has got to be a better way, but I hvnt worked with the iPad in that kind of situation to know,  I would think reaching out to apple,s business specialists is the best option.

    As explained above, it's not currently possible.

    I think I have a solution. It's a portable device called a Mi-Fi which acts like a Wi-Fi router, but it has 3G built-in (instead of connecting to a DSL or cable modem). This would allow you to use Wi-Fi Only iPads since the Mi-Fi device handles the 3G Internet connection. Here's a link to info on "Mi-Fi" at Wikipedia:

    So I'm assuming you would just connect your Wi-Fi iPad and HP printer to the Mi-Fi device, they'll both have access to the Internet, and AirPrint should just work.

    Not possible with any device — iPad or computer — unless that device has two network cards.  The same network card can not have two IP address just like a house can't have two street addresses.  Sure, Apple could put two network interfaces in the same device but VERY few users have a need that.  Same reason your computer only comes with one network card.  Very limited use case.  You are attempting to use a consumer product in a business environment.  Frustration will follow.

    Actually it worked just fine. It used wifi to print and 3G to get to the Internet.

    And it doesn't.

    The 3G port has one IP address and the wifi port has a different IP address.

    The 3G iPad does have two network interfaces. One for 3G and one for wifi.

    Most computers come with ethernet and wifi, two separate network interfaces.
