What is the maximum number of lines that can be printed on a roll?
There is no explicit limit on the number of lines that can be printed on a roll. However, as a practical matter, each printed line consumes memory and if you plan to save the printout as a JPEG photo to transfer it to your computer for physical printing or manipulation then we recommend that you keep the number of printed lines to not much more than 200 lines. Moreover, because the printed lines are saved each time the app is closed and restored when the app is next launched, it would be best to keep the number of printed lines to a reasonable number to prevent excessively long app launch times.

It does however apply when first launching the app after a device reboot or if the app was forcibly quit while in the background either manually by the user or by the OS under low system memory conditions.
