Views do not have to be connected to a window to print, only to be displayed
on screen. You merely need to create the view, draw into it, and send it a
print: message.
I have a fairly advanced example here:

You'll want to focus on the [MyDocument printDocument:] and [MyPrintView
initWithTextView:printInfo:columns:] methods.
