Inside Macintosh: Programmer's Guide to MacApp / Part 2 - Working With MacApp

Chapter 23 -
Working With Printing

This chapter describes how a standard print-handler object handles print menu commands such as Print and Print One. It also includes recipes and sample code that demonstrate how to

• work with printing (a general outline)
• create and initialize a standard print handler and associate it with a view
• change the default margin settings
• show page breaks in a view
• define a custom print-handler class to modify page strips
• turn on debugging support for printing in a debug version of your application

For a detailed overview of MacApp's printing support, see "Printing," beginning on page 230.

For related information, see "Saving a Document's Print Information," beginning on page 403, and "Recipe--Creating Views for Displaying and Printing Versus Printing Only," beginning on page 431.
