// Normalize the collated, # copies, numPages, first/last pages. Need to
//  make note of pageRangesAttr.
// Set up NSPrintInfo with the java settings (PageFormat & Paper).
// Create an NSView for printing. Have knowsPageRange return YES, and give the correct
//  range, or MAX? if unknown. Have rectForPage do a peekGraphics check before returning
//  the rectangle. Have drawRect do the real render of the page. Have printJobTitle do
//  the right thing.
// Call NSPrintOperation, it will call NSView.drawRect: for each page.
// NSView.drawRect: will create a CPrinterGraphics with the current CGContextRef, and then
//  pass this Graphics onto the Printable with the appropriate PageFormat and index.
// Need to be able to cancel the NSPrintOperation (using code from RasterPrinterJob, be
//  sure to initialize userCancelled and performingPrinting member variables).
// Extensions available from AppKit: Print to PDF or EPS file!
