print back to summary

public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException

Implements java.awt.print.Printable.print.

Prints the page at the specified index into the specified Graphics context in the specified format. A PrinterJob calls the Printable interface to request that a page be rendered into the context specified by graphics. The format of the page to be drawn is specified by pageFormat. The zero based index of the requested page is specified by pageIndex. If the requested page does not exist then this method returns NO_SUCH_PAGE; otherwise PAGE_EXISTS is returned. The Graphics class or subclass implements the java.awt.PrintGraphics interface to provide additional information. If the Printable object aborts the print job then it throws a PrinterException.

Parameters

graphics:Graphics: the context into which the page is drawn
pageFormat:PageFormat: the size and orientation of the page being drawn
pageIndex:int: the zero based index of the page to be drawn

Returns:int

PAGE_EXISTS if the page is rendered successfully or NO_SUCH_PAGE if pageIndex specifies a non-existent page.

Exceptions

PrinterException:: thrown when the print job is terminated.
