I have just brought the brother dc-135 all-in-one printer that was on hukd a week or so back. It works fine copying but i don't know how to get it attached to my laptop. I know i need a usb but should it have come with the printer, the laptop or can i buy one anywhere? are they universal so they fit any laptop and any printer? sorry if this seems silly but if anyone could help me by putting a link where i can just buy one, it would be great. Thanks in advance!
