I haven't been using printers for ages so I have a couple of questions: 1- How can I print four images/pages on 1 sheet using ios? I tried using OS 9 print option and Brother iScan app but I don't know how to do it. Print Pro from Readdle seems to have the option but I don't know how to use it. 2-How can I print on 2 sides/duplex using iOS? When I chose to print a website(wikipedia article) I got the options for double side but I didn't get it with images in the camera roll.
