                else
                {
                    // Create the first page and add it to the print 
job.

pages are queued.
                    while(true)
                    {
                        // Move the next page of data to the top of 
the print grid.

if the last page 
                        // was completely filled by the last grid 
data, queue it for printing.
                        // Test if there is data for another 
PrintDataGrid page.

exit the print loop.
                            printJob.addObject(thePrintView);
                            break;

page.
