Class Description

NSPrintOperation controls printing of an NSView. When invoked normally it will (optionally) display a standard print panel (NSPrintPanel), and based on the information entered by the user here as well as information about page layout (see NSPageLayout) tells the NSView to print it's contents. NSPrintOperation works with the NSView to paginate the output into appropriately sized and oriented pages and finally delivers the result to the appropriate place, whether it be a printer, and PostScript file, or another output.

setCurrentOperation: 

+ (void) setCurrentOperation: (NSPrintOperation*)operation;
Availability: OpenStep

Set the current NSPrintOperation to the supplied operation object. As this is currently implemented, if a NSPrintOperation is currently running, that operation is lost (along with any associated context), so be careful to call this only when there is no current operation.

Availability: OpenStep

Called by the print operation after it has finished running a printing operation.

context 

- (NSGraphicsContext*) context;
Availability: OpenStep

Returns the graphic contexts used by the print operation.

createContext
