7.1 Interfaces and Classes

Interface

Description

`Printable`

The `Printable` interface is implemented by each page painter, the application class(es) called by the printing system to render a page. The system calls the page painter's `print` method to request that a page be ren dered.

`Pageable`

The `Pageable` interface is implemented by a document that is to be printed by the printing system. Through the `Pageable` methods, the system can determine the number of pages in the document, the format to use for each page, and the page painter to use to render each page.

`PrinterGraphics`

The `Graphics2D` objects that a page painter uses to render a page implement the `PrinterGraphics` interface. This enables an application to get the `PrinterJob` object that is controlling the printing.

Class

Description

Book

Implements: Pageable
Represents a document in which pages can have different page formats and page painters. This class uses the Pageable interface to interact with a PrinterJob.

PageFormat

Describes the size and orientation of a page to be printed, as well as the Paper used to print it. For example, portrait and landscape paper orientations are represented by PageFormat.

Paper

Describes the physical characteristics of a piece of paper.

PrinterJob

The principal class that controls printing. The application calls PrinterJob methods to set up a job, display a print dialog to the user (optional), and to print the pages in the job.
