In this chapter you learn about using your printer and the resources associated with it. Some of the topics learned here can be retrofitted to previous programs. For example, threading might be useful in the database programs where there is a noticeable pause while network information is updated.

Using a Printer

Often a program generates data that you don't necessarily want to persist on disk, but that you might like to review at a later time without rerunning the program. Obviously, printed output of the data is one way to go. In this chapter, you examine some of the printer objects that should prove useful in your programs.

In the following Try It Out you write a program that can read and print a simple text file. Although a text file is used for the output to print, the methods used apply to almost any type of data.
