I need to print Invoice created by jetpack compose canvas or print lazyColumn directly like when print canvas in android

My comment was not to suggest that Java2D printing somehow magically works for a completely different toolkit that is Compose. It was to clarify the request.

Probably given the multi-platform aspirations of this framework, the simplest would be to provide a functionality to export canvas content to a PDF and have the underlying platform handle the PDF-to-print pipeline.

@kirill-grouchnikov thank you

Currently there is no such possibility. What probably could be tried is the following:

  1. Create test Window with the same content
  2. Grab its bitmap
  3. Find some java printing engine that accepts bitmap and pass the bitmap to it

Steps 1-2 are described in https://github.com/JetBrains/compose-jb/issues/368

Couldn't ComposeScene be used? With it you can draw to canvas instead of window.
