Here we don’t recommendthese formats for FotoPrisa Printer.4.3 Choose the appropriate image source for the fileto be printedTo get a perfect printout with FotoPrisa Printer, first, there are 3points needed to really take care of for choosing an appropriateimage input:Image sizeBefore we go into the topic, there are several important termsto know in advance.A digital image is composed of a minimum unit called pixel.With the variation of pixel properties, you can create variouseffects to the image.
