Toka prints on the paper size you choose, Letter or A4. It's on your profile, so a lesson never has to ask.
Choose a page size
Open your profile.
Under Print page size, click Letter or A4.
It saves straight away. Until you choose, Toka uses Letter for a family in the US and A4 everywhere else.
It's your own setting, so a co-parent with a different printer keeps theirs. The app's print settings use the same one.
Writing worksheets
A lesson's writing worksheet says which paper it prints on, such as Prints on Letter paper. To switch between Letter and A4, change your page size above. Every worksheet follows it, including ones you open from a child's view of a lesson.
In kids mode, a child's worksheets use a parent's page size. If both parents have chosen one, the parent who joined Toka first is used. A teen with their own sign-in can set their own on their profile.
