SUMMARY 739
Summary
Printing is a major aspect of any language, and it’s not a trivial topic. In my experience, many developers purchase controls with built-in printing capabilities to simplify the task of printing from within their applications. If you’re developing business applications, you should probably implement a few classes for printing the basic types of reports and reuse them throughout your application. You can even share them with coworkers, to make sure all reports have a consistent look.
The Framework provides a number of controls to simplify tasks such as setting up the printer and page properties and previewing your printouts before sending them to the printer. These tools can be used to generate very simple or very complicated printouts. The basic tools and the outline of the process don’t change. Your code, however, may become considerably more complicated.
