I just saw all the negative comments, and dont understand why people are having such problems. I always use the latest update. I printed several documents last night, and just used it to Scan a pix (first time use of scan). All worked perfectly. The APP has saved me a lot of time as I do not have to run up to the office to print, but can do it at the table with my iPhone or iPad. Now, having said that, I only seem to be able to print "attachments", like a pdf or jpg. While using my Comcast email reader, I havent figured a way to print the email itself, just the attachments. Anybody have an idea??
