I scanned a document using an HP Officejet 4630 Series, connected via USB to my Acer Aspire 5920. I intent to send that document as an attachment but when I do this, the file open as a firefox file and open in a tab and this address; file:///C:/Users/ADMINYO/Documents/Scan0001.pdf. The file properties, in the Type of fileline identify it as ''Firefox HTML Document (.pdf)''. But again, the printer is USB connected. In a second try, I turned off both the printer and the Laptop Wifi features having the same results. Any sugestion? Thanks.
