Vista - Brother MFC 420CN printer not printing

Please help! Said printer will not print wirelessly from my laptop. It prints just fine from my wife's PC that is hard wired directly to the router that the printer is hard wired to (CAT5). I have tried uninstalling the driver from the laptop & re-installing it, that didn't work. If I go into the printer properties and try to "Print Test Page" & if I open the active printers window, it tells me that the document has been sent to the printer and then printed. It then deletes the document from the queue, but nothing ever prints to the printer. Now, I go into the printers folder, right click on the printer, goto "Run as Administrator" click on properties and then try to "Print Test Page" from there it works fine.
I am logged onto the laptop as the administrator and I am the only person that uses this laptop. I haven't tried to use the printer in the last week or so, but prior to that, I haven't had any problems with it printing. I am running "Green Print" as my default printer, which converts all documents to PDF and then opens its own app & then gives me the option to print to the physical printer. Even if I try to bypass Green Print and print directly to the physical printer it will still fail.
