I believe that costs to record drawing first and replay later are negligible compared to actual drawing operations.
BTW, note that DrawData performs "RLE encoding" of resulting bitmap drawing which I believe should greatly reduce printer bandwidth in most common cases.

After that topic: http://www.arilect.com/upp/forum/index.php?t=msg&&th =1098&goto=3689#msg_3689
I agree...
Do I understandand correctly that the line in DrawDataOp:
Image m = dd->Render(ccy); //render some lines (rectangle of image)
implies on having not the whole aggImg but only some piece of it generated (or lines rendered) "on demand"?

Yes, it creates the "band" of the target width, but ccy height. DataDrawer should return consequentive (it that the right word? bands, starting with y = 0.
BTW, term "band" is adapted from Windows printing terminology and I believe that the very original meaning comes from those old matrix printers - when printing graphics, you need to send similars strips to the printer, covering the height of ink band.
