Windows print canvas
On Windows, react-native-print
needs an element in the visual tree to add the printable pages to.
It will look for a XAML Canvas
named RNPrintCanvas
and use it.
This needs to be added to the XAML tree of the screens where react-native-print
is used.
As an example, in windows/myapp/MainPage.xaml
from the react-native-windows
app template this can be done by adding a XAML Grid
with an invisible Canvas
alongside the ReactRootView
. Change windows/myapp/MainPage.xaml
from:
<Page
...
>
<react:ReactRootView
x:Name="ReactRootView"
...
/>
</Page>
to
<Page
...
>
<Grid>
<Canvas x:Name="RNPrintCanvas" Opacity="0" />
<react:ReactRootView
x:Name="ReactRootView"
...
/>
</Grid>
</Page>
