I have a client with a blackberry 8700 who's interested in wirelessly printing to a portable printer via bluetooth - or I guess IR would be fine as well if that's the only option.
He hasn't bought the printer yet, however I've really only found two viable portable printers on the market so far that will print at least 8x10, weigh under 5 pounds, and can run on internal batteries:
The Canon Pixma iP90 (there's also the same with a 'v' at the end - have yet to discover the difference)
The HP Deskjet 460 mobile printer.
Blackberry devices seem to not be officially supported by either printer at the moment - bluetooth or not. The canon officially supports windows mobile and palm OS and it seems like the HP doesn't officially support either of those, but they do officially endorse a third party product from Bachmann Software Welcome HP 460 Customers - PrintBoy Registration Page
Now on the title of that website I see it says "Wireless File and Print Solutions for ..., ..., .., and Blackberry Handhelds and Smartphones. Yet I don't see a mention of any product for a Blackberry anywhere else on that site.
So I guess it has come down to this - does anyone know of any way to print wirelessly - third party or not, from a Blackberry 8700 (or any other model, for that matter, if it will get me on the right track) to ANY reasonable portable printer?
