Adopting the Carbon Printing Manager

This chapter provides information that will help you convert printing code that uses the old Printing Manager so that your code uses the Carbon Printing Manager. The Carbon Printing Manager was designed to let Carbon applications take advantage of new features in Mac OS X, while still working correctly in previous versions of the Mac OS.

If you want to port an application that runs in Mac OS 9 and earlier versions of the Mac OS to one that runs in Mac OS X, you should read Inside Carbon: Carbon Porting Guide. The guide covers all porting topics, except for porting printing code, which is covered in this chapter.

Updating your application to use the Carbon Printing Manager is a straightforward process. These are the basic steps:

1. Remove all references to the Printing.h header file from your project.

2. If you are building your application so that is runs only in Mac OS X, make sure you link against the Application Services and Carbon frameworks. If you are building your application so that it can run in Mac OS 9 as well as in Mac OS X, you also need to add the CarbonLib library to your project.

3. Convert your code to use the new printing functions and opaque data types, as described in the following sections.
