Print to Size uses iOS’s built-in AirPrint system. Occasionally this printing system fails to produce a print for reasons unrelated to the app.
Possible solutions
- If no error is displayed but no print happens, please check the print queue in the Print Center to see if a job is paused.
- If you haven’t restarted your device in a while, try rebooting it. Many issues of this kind are fixed by rebooting.
- If your device’s storage is nearly full, please try to free some space then reboot.
Workaround
Print to Size includes the option to export your page as PDF or JPEG, which allows you to print it via any alternative method that is available to you, such as using your printer manufacturer’s own app (which typcially does not use the iOS built-in system but its own proprietary printing system) or even another device or computer.
