[edit] Overview

The QPrinter class is responsible for printing in Qt. Like QPixmap or QImage, it is a QPaintDevice. There is also the QPrintDialog class, enabling a variety of settings to be made at the printer. Under Windows and Mac OS X the class shows the print dialog of the system; otherwise, it uses a separate dialog. The user can manipulate all the settings in the dialog. But user must keep in mind some basic information while using these classes in the code.


[edit] Tips

It is better to predefine QPrinter and QPrintDialog before using them inside the code or else compilation process will not be successful because of no printer support.

#ifndef QT_NO_PRINTER
 
...
 
QPrinter printer(QPrinter::HighResolution);
 
QPrintDialog dialog(&printer, this);
 
...
 
#endif
