Bluetake BT200 problem

I pray there is an answer to this, I just for a bluetake bt200 printer adapter today

I pluged it in my hp deskjet 550 printer and it flashes a blue light every few mins, but i couldnt find it with any of my bluetooth computers.

I then pluged it in my sisters epson stylus printer and it was a steady blue light turned to pink and it was picked up by my pda

Is there a reason why it has not worked with my hp?

I love the hp, i need this thing to work

Thanks
