    My point is that MOST bluetooth phones will probably NOT have TCP... only UDP.
    While the bluetooth spec may support it, if it is not in most phones than
    mandating it for printing won't be very successful.

    It's right you could run IP over Bluetooth. Today there is only one profile
    describing how
    to implement a LAN access point, not a really LAN on Bluetooth, but is just a
    matter of time
    before this profile will be finished. But I am not sure the mobil phones and the
    PDA's will
    implement a whole TCP/IP stack just for printing. They have a WAP stack, so I
    think they
    would preferred to reuse the stack for printing to.

    Regarding bluetooth - my assumption was that there would be IP over BT. Then we
    can do plain old IPP rather than inventing something new - or am I missing
    something here.

    Regarding IR - the good thing about it is that ~100% of laptops and many PDAs
    have it today - and yet it is poorly exploited anywhere. Secondly it is an
    inherently point and shoot interface which make it ideal for things like
    printing where you are communicating with a specific piece of hardware as
    opposed to a virtualized service. I know there is IP over IR but that does not
    seem to be widely used.

    Carl-uno I think that we should put 'exotic transports' on the agenda of an IPP
    meeting soon becuase there is obviuosly interest and it is not in anybody's
    interest to have this fragment into lots separate efforts.

    A last IPP meeting, I can see you discussed the topic 'IPP over other
    and that Paul Moore metioned the infrared transport. In i-data we are working on
    the new wireless technoligy BlueTooth. I think in a few years you will not
    see the use of infrared soulutions anymore, but it will be BlueTooth. Ericsson,
    and the PDU's are going to implement BlueTooth in their products. In i-data we
    are working on a LAN profile to Bluetooth as well as on a Printing Profile. Our
    solution for printing over Bluetooth will be to use IPP over WAP. WAP is
    in some mobil phones today, and will be widely spread by the years. WAP looks
    a lot like HTTP. So I think it would be interesting to run IPP on the top of
    WAP. You
    would then be able to print from your PDA or mobil phone.
