As you've probably noticed Numbers makes it easy to multiple smaller tables on the same sheet. (see templates at File > New in the menu to see examples of effective document design in Numbers). So there's much less need to try to grab specific areas of a vast expanse of cells that you often have to work with in Excel.
But there is a way, and it's much quicker and easier than it sounds. Just select the range of cells in the Numbers table, here A489:H579 if I understand you correctly, type command-c to copy, launch the Preview App, type command-v to paste, and print from the Preview App. The result is generally very high quality.
