If you want to scan from computer will need the program installed.
I recently changed from XP to Windows 7 (64 bit)and am trying to network two computers. I have a tower (Main) and a Sony Vaio laptop. I downloaded the compatible printer program for my Brother MFC 8660dn into the tower. All functions perfectly for faxing, scanning, and printing. I have not downloaded the program onto the laptop and can print when hooked up to the home network. However, when I open Adobe Acrobat 9 and try to scan a document, no device shows up. Do I have to download the program into my laptop in order to scan, or is this a function I will not have on the laptop? The laptop is not directly plugged into the printer (the tower is).
