May be a daft question but anyway.
A local place has 'dongles' for sale at about 17 quid.
If I plug one of these into my laptop (Win2K) and one into my PC (Win98) could I send prints from laptop to printer attached to PC?
Also, could I at the same time have another plugged in to another laptop (WinXP) to do the same?
Would I need any other equipment/software?
Have I lost the plot?

The blootooth is the microwavs which make thing to talk to another thing.
My Uncle say that blootooth is nearly as good as the blacktooth but you must eat lot of the sugar.
Simply put blotooth is the foundation of the currently networkable enviromentt which depend on the radiowav to comunikate.
This in the turn make everything talk to the otherthing which make the world much more nice.
Is that simply enough?
I am having blootooth put in fiat, so I can make the stereo much better.

Yes, you could. That would be a wireless network of sorts. However, bluetooth has a very small range - just a few feet in practice. 802.11 "proper" wireless networks are bad enough, unless all your computers are in the same room bluetooth wouldn't really work.

Phil, thanks.
Actually the PC's are all within a few feet of each other, it's just the one with the printer attached is a tower unit and I'm too lazy to keep pulling it out of the desk to unplug the serial cable and plug it into one of the other machines.
Do you know how I would print from a machine via bluetooth? Presumably I would have to make the 'main' machine a print server of sorts?

no if the printer has bluetooth, you make the printer the printer server.

bluetooth is a bit like short range wireless usb, its a standard communication interface. you can connect up to 20 devices in one zone together, you can also network your pc's through it (not sure how secure, may depend on configuration)

But the printer is connected directly to the main PC. I know I can buy something to fit in the back of the printer to make that bluetooth but it's about £70.
Being a tight git I was looking for a cheaper alternative, if I have to spend 70 quid on the printer then 20 quid each on 3 dongles I think I'll just keep pulling the desk out and swapping the cable over!

in that case the pc with the printer attached needs to be a printer server. Sorry i thought the printer was bluetooth already.

if both pcs are in the same room, why use bluetooth, a couple of reasonable 100mbs network cards and some cable (remember to get link cable (not stuff to a hub)). as the banwidth on bluetooth is about 11mbs (not sure!). it will be faster and a lot more secure.

or could he not set the two computers up as a home network, and the printer would then be the default network printer!!!

Cheers Chaps, both good ideas, however I'm really looking for no added wires.
As for the security aspect, I'm surrounded by old biddies who wouldn't know a PC from a policeman, except for the neighbours who don't even have a car!

If you can get all the PC's to see each other through Bluetooth networking then you just need to share the printer on the PC, as in a normal network.

We've run a home Bluetooth network of sorts for just over a year. A couple of notes:

Bluetooth doesn't require line of sight, therefore it's not necessary for BT devices to be in the same room.

Range depends on whether you use Class 1 or Class 2 Bluetooth devices. Class 1 extends to 10m, Class 2 is up to 100m (although we've found that we need to be more precise in aiming the signals at greater distance).

Dongles or anything mains-powered seem more likely to be Class 2 devices -- although not necessarily so; anything hand-held is more likely to be Class 1 due to increased power consumption (in my experience, but this could be wrong).

Security shouldn't be a problem - in fact, BT can be more secure than WiFi (will try to dig up a recent report on this).

IMO, one thing to watch when buying dongles is the services available with the software provided. In my experience, this is what dictates what you can & can't do with your Bluetooth network.

VictorMeldrew:
I read that you also have a P800 & wondered if you've also tried setting up Bluetooth network services between PCs? I'm hoping that you or someone else has also tried, as I've hit some problems & think it's software / services related, but would like confirmation before buying additional hardware.

For example, I can get my PDA to join our home network & surf the Internet etc. using BT, but can't manage to get the laptop to see all the network resources it normally does via Ethernet. The only thing I can see from it is the limited Bluetooth network services that the software provides. I eventually came to the conclusion that a dedicated Bluetooth network access point would be required instead of a pair of dongles - does this seem reasonable, or am I just missing something?

Any info / advice would be much appreciated.

I have a P800 and a bluetooth dongle. Seems to work very well.
I'll be installing a 54g wireless network at home at some point so I can browse from anywhere but I will have to make provision for bluetooth for the P800.

The stuff I have read about bluetooth is that it is intended to replace cables not do lots of netwkring.

I also use a bluetooth headset with the P800 which works well (apart from the fact that I cannot hear a bloody thing in the cerbera)..
