It can scan up to 11"X17" which is the size of my old large art book, which means that I can save them on here or on my computer in general so that when the art book falls apart (which it is already doing) that I will have them. And it also means that I dont have to worry about my pictures being too big to scan anymore, even though i still have an artbook that is 14"X 18"(i think that is the dimensions, it is definitely bigger than the scanner)
It is a printer scanner that I can email and it will print whatever I want from wherever I am
so it is obviously wireless, it can be connected through usb cable, wifi or email
it dose 2 sided printing and can print up to 11"X19" I believe because of how large the second tray is. I like it
