Saving a large turtle graphics image from the entire canvas, not just the window

问题

After looking for answers all around, I find lots of help and guidance on how to save a file either using turtle screen or tkinter canvas mixed with the turtle module. I'm drawing a large image and the windows size is fine and scrollable, letting me see the entire image. But when I try to save the image to postscript, I only get the window view, not the entire canvas. Cannot find out how to proceed, any tips?

There might be an answer in How can I convert canvas content to an image? but I cannot see how to connect tkinter with turtle. Can someone elaborate on that?
