Can I edit a .tiff file with this application? Can I add signature, lines, notes, highlights, etc.?
ImagePrinter is a freeware application that was developed to help you print images. It supports .tiff files but you cannot edit these files. The only preferences that you can change are: set the paper size, margins, color and availability. Therefore, if you want a program that can help you edit your .tiff files, I recommend you to go to Google Search or you can search for such applications on Software Informer database.
