Scans can be saved to computer storage (hard drive, flash drive, etc.). The scan process allows you to specify the file type (JPG, PDF, TIFF) and when scanning is completed the printer will send the image to the computer you choose. Once on your computer you can copy/move the file to the location of your choice. I have not used this unit to scan slides but it does scan pictures very well.
From the user manual: "This machine supports 35 mm negative and positive film strips (standard state of developed film, with six frames in each strip) as well as 35 mm mounted positive slides (one frame per mounted slide).
Up to six film strip frames or four mounted slide frames can be scanned continuously."
You can save to a computer, and possibly the USB drive.
Yes you can. Once scanned you can do whatever you need w the digital file. We found this printer to be very easy to set up and to use. It is the best value for your money. The print quality is very professional. Although it does not have a fax it more than makes up for the lack of it in quality and ease of use.
It has the ability to select what it is your trying to scan; JPEG, DOC, photo,etc. but I did have issues with scan feature and driver use for the scan option. I'm currently waiting for Canon tech support as my scan feature doesn't even work even though the application is clearly on my PC.
I'm not a professional photographer but I would think not. The slide image size against the white background of the scanner cover is just too small an image to allow for decent information to be digitized. You could however, at some expense have a positive print (3x5 or more) made from the slide and scan that photo in the usual way or have them create the digital file with their specialized equipment. Pros and camera shops should be able to steer you in the right direction.
