Duplex Print Helper - print on both sides, even with a printer that can't. Print the odd pages first, flip the stack, then print the even pages. That's the whole trick. This app makes the two PDFs for you and shows you the page order before anything goes to paper, so you don't waste a whole stack finding every back page upside down. One-time unlock. No subscription, no ads, no account to create, and your PDFs stay on your device. [What you get] - Two ready-to-print PDFs: front (odd pages) and back (even pages). Print them in the app, or export and share them to print anywhere. - A preview of both sides and the exact page order before you print. - Back pages ordered for top-feed or bottom-feed printers - the order changes with your printer. - If the backs still come out reversed, tap "Switch order" on the result screen. No re-splitting needed, and the choice is remembered. [3 steps] 1. Open your PDF 2. Check the front/back preview and choose how your printer feeds paper 3. Print the front PDF, flip the stack, print the back PDF [Why people use it] - Kids' homework - teachers keep asking for double-sided printouts - Office documents - the work printer has no duplex - Home - save paper without buying a new printer [Also included] - Convert Word, images, e-books and other formats to PDF - Works with inkjet, laser and most printers - Simple enough for anyone, including seniors --- If this saves you a ream of paper, a 5-star review helps more people find it!
