We haven't managed to pair the devices. We did try putting the laptop next to the printer and PC to see if I could pair the devices which is the only way I could get my son's and grandson's mobile 'phones paired with my laptop. Once done though, I can download photos from my son's 'phone to my PC via bluetooth when his mobile is not near to my laptop.
If I right click on the printer icon on my laptop, under sharing it states the printer will not be available when the computer is sleeping or turned off, which is why we were hoping to add the same printer via bluetooth, so that OH's PC will not have to be turned on when I want to print.
Of course, if the only way Bluetooth will work is if I sit by his PC and printer, then I may as well just run upstairs where the PC is and turn on OH's PC and then use my laptop to send things to print in the usual way.
I'm sure there must be some way to set up a printer using Bluetooth. When I go to Control Panel, Printers, add a printer there is an option for Bluetooth when I click on that it states "select the printer you wish to install from the list". The only problem there is no list and unlike when trying to add a shared printer by name, there is no such option for Bluetooth.
