The Java Print Service (JPS) API extends the current Java 2D printing features to offer the following functionality: Application discovers printers that cater to its needs by dynamically querying the printer capabilities. Application extends the attributes included with the JPS API. Third parties can ...
You have already learned how to use the Printable interface to print a single page document. However, documents are usually more than one physical page in length. Pagination is the process of identifying the location in a document where page breaks and printing accordingly. In case of printing ...
