Problem: With a one page poster I wanted to print two copies (approx A5) per A4 page to save paper. Now normally you could do this with a print driver at the point of printing. But wanted to save/send this image to someone else, and tried to do it all from an iPad/iOS.
Solution: Working from an image in Photos (app) convert to a one page .pdf via PDF Converter (app). Use PDF Expert (app) to duplicate that page. Now print the two page .pdf via PDF printer (app). Rather than print to a physical printer, print to a PDF printer which allows you to specify two pages per sheet, scaled to fit. Save the resulting .pdf which now has two copies on one sheet for future use.
This is a general process to get used to on iPad’s which seems complex but in reality is straightforward if you have the right apps and the right approach. Many iPad/iOS users I find think in single steps rather than multiple. But if you can think through multiple steps this makes more possible.
Postscript: might be interesting to automate something like this using Workflow (app) or similar, but I’m not sure how possible that might be. …off to investigate…
