At home I have a bluetooth print server (plug it in to the printers USB socket instead of the USB cable from the printer)
With XP SP1 it worked fine as you had the option to skip pairing (there is no default pairing code with the print server)
The problem with SP2 is that ALL devices must be paired and by not inputting a pairing code, the printer is rejected!
The print server is made by NEWlink:-
