We have a 105 and 550 and need to scan back to a pdf. I'm pretty sure it only works on the pc side, but the software I have is pretty old. Is the 105 compatible with what scan software and which version of Acrobat? Thanks > Eugene Montanez ZAP Printing & Graphics 127 Radio Rd Corona, CA 92879 951-734-8181 Zapit at zapcolor.com
