erm how did it get nto the printer?
let us suppose you put it there and it is a scanner
scan with pdf option
and make sure that when they ask for a path you specify laptop
hey if it is a printer scanner
then plug it into your computer
and if your are on the internet it will suck the driver from the internet
and operate the scanner from your computer
helluva a faff around - then after a few goes
you think oh it is easy
Please can we have some further details about exactly what is that you're trying to do? Are you trying to scan a document and then print from the scan (so that, in effect, you're photocopying it) or is it something different that you're aiming for?
(As SA has suggested, knowing the make and model of your printer might help too).
