I have Brother printer/scanner combo, with 2 macbooks (wife + me). One computer prints/scans, no dramas, never had to do anything, fine out of the box.. The other computer has never worked to print. Can scan, but doesn't print.
Same computers, same operating system, same wifi connection. So if my wife wants to print she has to print from her phone (which will happily airprint, no setup required) or send it to me, and I press 'print'.
wtf
There's still a few things that could cause that. Firewall for one, but presumably you both have the same setup. Also the printer wifi band, if you opted 5ghz signal on yours and the wife went with 2.4 that'll do it. There's other things surely, but I'm not very tech savvy.
