public abstract class CachedPrinting
extends SimplePrinting

Cached Printing. The paradigm of this concept is - back to the roots: Don't call me, I'll call you. This means e.g., I read some database tables, compute some stuff and put it out in the sequence as I am used to. The result is buffered, at the moment in Vectors. Later, the result is provided in a sequence, the renderer (printer) wants to retrieve it (e.g. page 1, page 2, again page 1). This principle assumes that Graphics and PageFormat stay constant for all pages!
