I simply want to take a pdf file, print 2 pages onto one side of one page, and have them collated to be able to fold into booklet form. I want to do this from an iPhone (iOS) with the app, and from a simple printer (prints only one-sided). I cannot find any way to do this simply. I also have a purchased version of Adobe Acrobat (which should not even be necessary to accomplish this menial task) but it doesn’t seem to be much help converting the PDF to booklet on iOS either. If I can get the printer to print the correct “pages” side by side on the paper, I can easily print the first “half” of the book, and then send those pages through the printer again to print the other “half” of the book, on the back-side. I just cannot find a more simple way to do this. It should not be a difficult feature to add to the HP Smart App- and it should already be there in my opinion. Perhaps it is and I cannot find it? But it would be great to know the easiest path to take to do this….. thanks in advance for any advice!
